TITLE: Does anyone know of a complete list of theorems?
QUESTION [6 upvotes]: It seems like this should exist somewhere but I can't seem to find it anywhere. I am looking for some book or encyclopedia with a list of common mathematical theorems or at least the ones that are common enough to have their own names. Can anyone give me some advice?

REPLY [10 votes]: You can try: 
(1) Wikipedia's list of fundamental theorems
(2) Wikipedia's list of lemmas
(3) Wikipedia's list of misnamed theorems.
