Gaj's Latin alphabet (Serbo-Croatian: Gajeva latinica / Гајева латиница, pronounced [ɡâːjěva latǐnitsa]), also known as abeceda (Serbian Cyrillic: абецеда, pronounced [abetsěːda]) or gajica (Serbian Cyrillic: гајица, pronounced [ɡǎjitsa]), is the form of the Latin script used for writing Serbo-Croatian and all of its standard varieties: Bosnian, Croatian, Montenegrin, and Serbian.

The alphabet was initially devised by Croatian linguist Ljudevit Gaj in 1835 during the Illyrian movement in ethnically Croatian parts of the Austrian Empire. It was largely based on Jan Hus's Czech alphabet and was meant to serve as a unified orthography for three Croat-populated kingdoms within the Austrian Empire at the time, namely Croatia, Dalmatia and Slavonia, and their three dialect groups, Kajkavian, Chakavian and Shtokavian, which historically utilized different spelling rules.

A slightly modified version of it was later adopted as the formal Latin writing system for the unified Serbo-Croatian standard language per the Vienna Literary Agreement. It served as one of the official scripts in the unified South Slavic state of Yugoslavia alongside Vuk's Cyrillic alphabet.

A slightly reduced version is used as the alphabet for Slovene, and a slightly expanded version is used for modern standard Montenegrin. A modified version is used for the romanization of Macedonian. It further influenced alphabets of Romani languages that are spoken in Southeast Europe, namely Vlax and Balkan Romani.
