In Dungeons & Dragons (DnD) and other RPGs, AC stands for "armor class." A player character's (PC) armor class determines how hard they are to hit in combat, and a Dungeon Master (DM) will often ask players what their AC is while attacking with non-player characters (NPCs). NPCs also have ACs, and players' attack rolls must either meet or beat an NPC's armor class to hit.
In the 5th Edition of D&D, each player character's base AC is 10. This base AC can be modified in a number of ways, including by armor, spells, and class-based abilities. Thankfully, online character sheets (such as those available through DnDBeyond.com) can now track players' armor classes for them, allowing them to focus on casting spells rather than calculating sums.
