Topi is a Finnish male given name, which is a shortened form of the name Topias.

In the Finnish almanac, the name was listed as Tobias from 1708 to 1889 and as Topias from 1890 to 1928, and it has been in use again since 1950 on November 2nd. The shortened form Topi was added to the almanac in 1929. Topi is also a common nickname for Toivo.
