Edwin Oscar Hall (1810–1883) was a businessman who was appointed Minister of Finance by Kamehameha III, serving in that capacity for one year.

Hall and his wife Sarah Lyons Williams were part of the Seventh Company of missionaries sent to the Kingdom of Hawaii by the American Board of Commissioners for Foreign Missions.

On December 5, 1834, one month after their marriage, the couple sailed out of Boston for Hawaii, then known as the "Sandwich Islands", on the merchant ship Hellespont, docking in Honolulu Harbor on June 6, 1835.

Also on board were bookbinder Henry Dimond and his wife, school teachers Lydia Brown and Elizabeth M. Hitchcock, and missionary Rev.

Upon Lunalilo's death, King Kalākaua formed his own cabinet, and Hall was replaced by Hermann A. Widemann on February 17, 1874.
