Theodosia is a feminine given name of Greek origin meaning "giving to God".

It is a feminine version of the Greek name Theodosius.

[1][2] The name was most popular in the United States in the 1700s and 1800s and has been rare since.

It has increased in use in recent years for American girls in part due to the popularity of the musical Hamilton, which features a song entitled Dear Theodosia.

The musical includes as characters fictionalized versions of the historical figures Aaron Burr and his daughter Theodosia Burr Alston.
