Joshua Hall (October 22, 1768 – December 25, 1862) was an American legislator who served as the eighth governor of Maine for 34 days in 1830.

After Governor Enoch Lincoln died in office, he was succeeded by the then Maine Senate president Nathan Cutler.

The Maine Supreme Court, however, ruled that Cutler could not remain in office as Governor past the expiration of his Senate term on January 6, 1830.

Hall as the new President of the Maine Senate was then sworn in as acting Governor, serving until the inauguration of Jonathan Hunton on February 9, 1830.

Hall then retired from politics and returned to preaching.
