When do you get your reaction back?

Somehow this has not come up yet but when do reactions reset? Is it one per round of combat or one per each of your turns?

I can think of a bunch of complicated ways this could work.

Top of initiative order is what I would think. But that's just going off of my gut

Once our turn in combat comes around, you have one Action, one Bonus Action, and one Reaction. The first two are used only on your turn. The latter can be used any time before your next turn begins. Once your next turn comes around, you get all three back.

DBZ has it right.
When you take a reaction, you can't take another one until the start of your next turn.
