There's not a lot of material published by WotC for 5e (relative to previous editions), nor is there planned to be. However, there are playable races for D&D scattered around in a few different locations in published products that people may not even know about. What are all the playable races, and where can one find each?
To be clear, we're talking about first party D&D 5e materials published by Wizards of the Coast.
Both "official" races (sanctioned for Adventurers League Play) and others, like races from Unearthed Arcana or from other WotC sources outside the D&D team that are less canonical, are of interest, but please designate whether they're considered official and sanctioned or not.
