Yes. X-Men: Apocalypse does have a post-credit scene.
Writer/producer Simon Kinberg confirmed a post-credit scene.
Slight spoiler/tease follows (nothing too specific) from Kinberg:
“It’s a nod toward potentially a lot of different movies. I mean certainly the Wolverine movie is related to what happens at the end of it, but there’s also another character that’s introduced, at least in name, in the tag and he could show up in any host of different X-Men films. Maybe a Gambit movie, maybe another X-Men movie.”

Synopsis:
Following the critically acclaimed global smash hit X-Men: Days of Future Past, director Bryan Singer returns with X-MEN: APOCALYPSE. Since the dawn of civilization, he was worshipped as a god. Apocalypse, the first and most powerful mutant from Marvel’s X-Men universe, amassed the powers of many other mutants, becoming immortal and invincible. Upon awakening after thousands of years, he is disillusioned with the world as he finds it and recruits a team of powerful mutants, including a disheartened Magneto (Michael Fassbender), to cleanse mankind and create a new world order, over which he will reign. As the fate of the Earth hangs in the balance, Raven (Jennifer Lawrence) with the help of Professor X (James McAvoy) must lead a team of young X-Men to stop their greatest nemesis and save mankind from complete destruction.
