APA In-Text Citation for Multiple Authors
Your bibliography
0 sourcesAPA In Text Citation Multiple Authors follows two rules in APA 7th edition: for two authors, name both every time; for three or more authors, name only the first author followed by et al. from the very first citation onward.
What is the rule for multiple authors in APA?
APA 7th edition sets a hard cutoff at three authors. Two-author works list both surnames in every citation. Works with three or more authors are shortened to the first surname plus et al. in every citation, including the first. The ampersand appears only inside parentheses.
This differs from APA 6th edition, which listed up to five authors on first mention. In the 7th edition there is no “first-time-in-full” step for three-plus authors — you use et al. immediately.
How do you cite two authors in text?
For a work by exactly two authors, cite both surnames every single time you reference the source. Use an ampersand (&) between the names inside parentheses, and the word “and” when the names appear in your running sentence.
ParentheticalReading fluency improves with repeated exposure (Ramirez & Chen, 2021).
NarrativeRamirez and Chen (2021) found that reading fluency improves with repeated exposure.
Never abbreviate a two-author citation to et al. Both names stay for the life of the paper.
How do you cite three or more authors?
For three, four, five, or more authors, name only the first author’s surname followed by et al. and the year. This applies from the first citation — there is no expanded first reference in APA 7. The Latin abbreviation et al. means “and others” and always takes a period after “al.”
ParentheticalSleep loss impairs working memory (Okafor et al., 2022).
NarrativeOkafor et al. (2022) reported that sleep loss impairs working memory.
Note the punctuation: “al.” always ends with a period, but no comma separates the surname from et al. A comma follows before the year.
What does a multiple-author citation look like?
- First author surname — only the lead author is named; co-authors are hidden behind et al.
- et al. — stands in for the second and all remaining authors (three-plus works)
- Comma — separates the author element from the year
- Year — publication year of the cited work
- Locator — optional page or paragraph number for a direct quotation
Author count at a glance
Use this table to pick the correct form instantly. The parenthetical column uses the ampersand; the narrative column uses “and.”
| Authors | Parenthetical | Narrative |
|---|---|---|
| One | (Alvarez, 2020) | Alvarez (2020) |
| Two | (Ramirez & Chen, 2021) | Ramirez and Chen (2021) |
| Three | (Okafor et al., 2022) | Okafor et al. (2022) |
| Four+ | (Nguyen et al., 2019) | Nguyen et al. (2019) |
| Group (first) | (World Health Organization [WHO], 2021) | World Health Organization (WHO, 2021) |
| Group (later) | (WHO, 2021) | WHO (2021) |
The reference list entry is different: there you list up to 20 authors in full, and for 21 or more you name the first 19, insert an ellipsis, and add the final author.
How do you cite group or organization authors?
When the author is an organization with a recognizable abbreviation, spell out the full name at first mention and give the abbreviation in brackets; use the abbreviation alone thereafter. Groups without a familiar acronym are spelled out every time.

Later (parenthetical)(CDC, 2023)
No abbreviation(Stanford History Education Group, 2020)
How do you avoid ambiguous et al. citations?
If two different works shorten to the identical first-author-plus-et al. form and year, spell out as many surnames as needed to tell them apart, then add et al. for the rest. This keeps every in-text citation pointing to exactly one reference-list entry.
Suppose you cite both Patel, Rossi, and Kim (2021) and Patel, Diaz, and Wu (2021). Both would collapse to “Patel et al., 2021.” Instead, write them as:
Distinguished A(Patel, Rossi, et al., 2021)
Distinguished B(Patel, Diaz, et al., 2021)
Also watch for same-surname, same-year different lead authors: if two first authors share a surname, APA does not require initials for et al. groups, but expanding names as above resolves any genuine clash.
Two works cited together
When you support one point with several sources at once, order them alphabetically by first author and separate them with semicolons inside a single set of parentheses.

How accurate is this guide, and what are its limits?
Every rule and example here reflects APA 7th edition, the edition in force since October 2019. The examples use invented but realistic author names and are formatted exactly as APA prescribes. Still, three cautions apply.
- Edition matters. If your instructor requires APA 6th edition, the three-author rule is different — 6th edition listed all authors (up to five) on first citation. Confirm which edition your course uses.
- In-text vs. reference list. The et al. shortening is an in-text rule only. Your reference list still names up to 20 authors in full, so never copy the et al. form into your bibliography.
- Generators still need a human check. Automated tools handle the common cases well but can misjudge group authors, missing dates, or ambiguity cases. Proofread against these rules.
Frequently asked questions
Do you use et al. for two authors in APA?
No. In APA 7th edition, a two-author work always lists both surnames in every citation. The et al. abbreviation is reserved for works with three or more authors.
When do you use et al. in APA 7th edition?
Use et al. whenever a source has three or more authors, and use it from the very first citation. There is no expanded first reference in the 7th edition.
Is it “and” or “&” between authors?
Use the ampersand (&) inside parentheses and the word “and” when the author names run in your sentence. This applies to two-author works.
Does et al. need a period?
Yes. “Et” is a complete word, but “al.” is an abbreviation of “alii,” so it always takes a period. Write et al. — never “et al” without the period.
How many authors do you list in the APA reference list?
List up to 20 authors in full in the reference list. For 21 or more, name the first 19, add an ellipsis, then give the final author’s name.
How do you cite a source with no author?
Move the title into the author position. Use a shortened title in the in-text citation, italicizing or quoting it as it appears in the reference list, followed by the year.
