F.3d stands for Federal Reporter, Third Series, a legal citation abbreviation.

Third series of West's Federal Reporter, publishing precedential opinions of the US courts of appeals from 1993 until 2021, when it closed at volume 999. Countless current precedents on civil procedure, criminal law, employment and constitutional questions are cited to it.

Example: Zeran v. America Online, Inc., 129 F.3d 327 (4th Cir. 1997), gave Section 230 its broad early reading.

Usage notes

Only opinions designated for publication appear in it; most nonprecedential rulings went to the Federal Appendix (F. App'x) from 2001 to 2021. Because one reporter covers every circuit, the citation must name the circuit, as in "(9th Cir. 2010)". Write it closed up, with no space before "3d".
