It's become incredibly difficult to keep track of the champions in boxing.
You've got interim confusion, emeritus nonsense and that's not to mention the diamond, silver and supreme shenanigans that are going on.
For this quiz, we've decided to focus on the four major organisations - WBA, WBC, IBF and WBO - and so as not to make it entirely impossible, we've also concentrated solely on the 17
male weight divisions - minimumweight to heavyweight.
There are a couple of vacant belts right now so feel free to answer "vacant" for those titles.

We don't expect anyone to get 100 per cent here but hardcore boxing fans should be looking at getting over 75 per cent.
Best of luck and let us know how you get on.
