Douglas Gunn (August 31, 1841 – November 26, 1891) was an American scholar, publisher, pioneer and Republican politician from California.

During this time Douglas Gunn learned the newspaper trade, working for the San Diego Union.

Gunn was elected upon the resignation of his predecessor, Will Hunsaker, after less than one year in office due to substantial conflict with a partisan council.

Prior to Hunsaker, the formerly bankrupt city had been governed by a state-controlled board of trustees for 35 years.

Gunn died in November 26, 1891, and is buried at Mount Hope Cemetery in San Diego, along with his parents.
