Hempstead Washburne (November 11, 1851 – April 13, 1918) was a Republican attorney and politician from Illinois who served as Mayor of Chicago from 1891 to 1893.

Hempstead Washburne was born in Galena, Illinois on November 11, 1851, and attended Maine's Kents Hill School.

[2] Washburne's final act as mayor was to submit vetoes of two ordinances that the council had already passed, one which served the interests of the Midland Elevated Railway (which stockbroker James R. Keene held significant stake in) and another which would have granted the Hygeia Springs Company permission to supply water into the city.

[3] After leaving the mayor's office, Washburne resumed practicing law, and became active in several business ventures.

[5] In 1883, Washburne married to Annie M. Clarke (1856-1939), a stage actress and the daughter of a prominent Chicago banker; they were the parents of four children.
