John E. Mullally (October 22, 1874 – January 15, 1912) was an assassinated American politician and saloon owner.

[1] He was elected to the California State Assembly from the 30th District in San Francisco, serving from 1911 until the time of his death in 1912.

[5] His life was cut short on January 15, 1912, when three people disguised as soldiers from the Presidio, who had been conducting a string of robberies, chose the saloon he owned at 116 Eighth Street as their next target.

Mullally's wife, May, and brother James, a fireman at a neighboring station, stayed with him until an ambulance took him to a nearby hospital, where he died while anesthesia was being administered.

He was buried at Holy Cross Cemetery in Colma, California.
