APA in-text citation helps readers see which source supports a quote, paraphrase, statistic, or idea in your paper.
Instead of placing full source details in every sentence, APA uses a short author-date citation that connects to a full entry on the References page. This guide explains how APA in-text citations work, when to use parenthetical or narrative citations, and how to handle common situations like multiple authors or missing source details.
Quick Answer to APA In-Text Citation
An APA in-text citation usually includes the author’s last name and the publication year. It appears in the body of your paper and points readers to the full source entry on the References page.
Basic APA parenthetical citation:
(Author, Year)
Example:
Students often revise more effectively when they receive feedback before the final draft (Miller, 2023).
Basic APA narrative citation:
Author (Year)
Example:
Miller (2023) found that students often revise more effectively when they receive feedback before the final draft.
For direct quotes, include a page number:
(Miller, 2023, p. 42)
The in-text citation should match the first author and year in the reference entry.
What Is an APA In-Text Citation?
An APA in-text citation is a short citation placed inside the paper whenever you use information from a source. It gives readers enough information to find the full citation on the References page.
APA style is common in psychology, education, nursing, business, communication, public health, and social sciences. These fields often value the date of research, which is why APA citations include the publication year.
For official examples, students can review the APA Style guidance on in-text citations.
APA in-text citations are used when you:
quote exact words
paraphrase a source idea
summarize research findings
use statistics or data
refer to a study, theory, or report
mention a claim that is not common knowledge
You do not need to cite your own ideas or general common knowledge, but you should cite any specific information that comes from another source.
Parenthetical vs. Narrative APA Citations
APA uses two main types of in-text citations: parenthetical and narrative.
Citation Type | How It Works | Example |
|---|---|---|
Parenthetical citation | Author and year appear in parentheses. | Feedback supports revision (Miller, 2023). |
Narrative citation | Author appears in the sentence; year appears after the name. | Miller (2023) explains that feedback supports revision. |
Use a parenthetical citation when the focus is on the idea. Use a narrative citation when you want to emphasize the author or study.
Both forms are correct. The best choice depends on how the sentence is written.
APA In-Text Citation for One Author
For one author, include the author’s last name and the year.
Parenthetical example:
Clear assignment instructions can help students write stronger research papers (Johnson, 2022).
Narrative example:
Johnson (2022) explains that clear assignment instructions can help students write stronger research papers.
The author’s first name, initials, article title, publisher, and URL do not belong in the in-text citation. Those details appear on the References page.
APA In-Text Citation for Two Authors
For two authors, include both last names every time you cite the source.
Parenthetical example:
Peer feedback can help students identify unclear claims in early drafts (Parker & Lee, 2021).
Narrative example:
Parker and Lee (2021) found that peer feedback can help students identify unclear claims in early drafts.
Use an ampersand & inside parentheses. Use the word and in the sentence.
APA In-Text Citation for Three or More Authors
For sources with three or more authors, use the first author’s last name followed by et al.
Parenthetical example:
Online learning habits can affect how students manage research assignments (Nguyen et al., 2023).
Narrative example:
Nguyen et al. (2023) found that online learning habits can affect how students manage research assignments.
The phrase et al. means “and others.” Include the period after al. because it is an abbreviation.
APA In-Text Citation With Page Numbers
Page numbers are required when you quote exact words from a source. They are also useful when you refer to a specific part of a long source.
Direct quote example:
“Feedback is most useful when students can apply it before the final draft” (Miller, 2023, p. 42).
For a page range, use pp.
(Miller, 2023, pp. 42–43)
If the source has no page numbers, such as a webpage, use another locator when available.
Paragraph example:
(University Writing Center, 2024, para. 5)
Section example:
(University Writing Center, 2024, “Revision Strategies” section)
For paraphrases, APA does not always require page numbers, but your instructor may prefer them when you discuss a specific passage.
Complete APA In-Text Citation Example
Here is a complete example showing how an APA in-text citation connects to the References page.
Source information:
Author: Rebecca T. Miller
Year: 2023
Book title: Writing With Evidence in College
Publisher: Beacon Academic Press
Page quoted: 42
Sentence with paraphrase:
Strong academic writing depends on clear source use, organized evidence, and careful revision (Miller, 2023).
Sentence with direct quote:
Miller (2023) explains that “evidence works best when readers can see why it matters” (p. 42).
Reference entry:
Miller, R. T. (2023). Writing with evidence in college. Beacon Academic Press.
This example is correct because the in-text citation includes the author’s last name and year. The direct quote also includes the page number. The reference entry begins with the same author and year, so readers can easily match the in-text citation to the full source.
Notice that the book title does not appear in the in-text citation. In APA, the short citation points to the full reference entry, where the title and publisher are listed.
APA In-Text Citation With No Author
If a source has no author, use the title or a shortened version of the title in the in-text citation.
Reference entry:
How to prepare for a college research paper. (2024, March 14). Student Academic Skills Center. https://www.example.edu/prepare-research-paper
In-text citation:
(How to Prepare, 2024)
If the title is long, shorten it to the first few meaningful words. Use title case in the in-text citation, even though the reference entry uses sentence case.
Do not write “Anonymous” unless the source actually lists Anonymous as the author.
APA In-Text Citation With No Date
If a source has no date, use n.d. for “no date.”
Example:
University writing centers often explain plagiarism as both a citation issue and an academic integrity issue (University Writing Center, n.d.).
If there is no author and no date, use the title and n.d.
(Guide to Academic Research, n.d.)
Do not guess a publication date. Use only a date that is clearly listed for the specific source.
APA In-Text Citation for Websites
For a website, use the author or organization and the year.
Example with organization as author:
Students should evaluate online sources for authorship, evidence, and purpose before citing them (University Writing Center, 2024).
Reference entry:
University Writing Center. (2024, March 12). How students can evaluate online sources. https://www.example.edu/evaluate-online-sources
If the webpage has no individual author but an organization clearly created the page, use the organization as the author. If no author or organization is listed, use the title.
APA In-Text Citation for Multiple Sources
When several sources support the same point, list them in the same parentheses in alphabetical order and separate them with semicolons.
Example:
Several studies have found that early feedback can improve student revision habits (Garcia, 2021; Johnson, 2022; Miller, 2023).
Use multiple citations only when each source clearly supports the same statement. Do not overload one sentence with sources that are only loosely related.
APA In-Text Citation vs. APA Reference Entry
APA in-text citations and reference entries work together, but they are not the same.
APA Element | Where It Appears | Example |
|---|---|---|
In-text citation | In the body of the paper | (Miller, 2023) |
Reference entry | On the References page | Miller, R. T. (2023). Writing with evidence in college. Beacon Academic Press. |
The in-text citation is brief. The reference entry gives the full source details. Every in-text citation should usually have a matching reference entry, and every reference entry should usually be cited in the paper.
Common APA In-Text Citation Mistakes
Mistake | Correct Approach |
|---|---|
Forgetting the publication year | Include author and year in APA citations. |
Using MLA-style author-page citation | Write (Smith, 2023), not (Smith 42). |
Leaving out page numbers for direct quotes | Include page numbers for exact wording. |
Using first names in citations | Use last names only. |
Citing the URL in the text | Use author and year, not the URL. |
Not matching the References page | Make sure each citation matches a full reference entry. |
Using “Anonymous” incorrectly | Use “Anonymous” only if the source says Anonymous. |
Putting the citation too far from the source idea | Place the citation near the quote or paraphrase. |
Tips for Checking APA In-Text Citations
Before submitting your paper, scan every paragraph that uses source material. Check that each quote, paraphrase, statistic, or research finding has a clear citation.
Next, compare in-text citations with the References page. If your paper cites (Miller, 2023), the References page should include a source beginning with Miller and 2023.
Then check direct quotes. Every direct quote should include a page number, paragraph number, timestamp, or another locator if available.
Finally, make sure you use APA consistently. Do not mix APA author-date citations with MLA author-page citations or Chicago footnotes.
