Thomas Hare (March 28, 1806 - May 6, 1891) was an English solicitor who was involved in the theory and advocacy of election methods.

Hare lends his name to the following:

• a system of proportional representation, also known as Single Transferable Vote (STV)
• the single-winner case of STV, instant-runoff voting
• a particular quota being used by STV, the Hare quota
• a seat allocation method, also know as the largest remainder method or Hamilton's method
