Mulhall is a town in Logan and Payne counties in the U.S. state of Oklahoma. The population was 239 at the 2000 census. It is part of the Oklahoma City Metropolitan Statistical Area.
The town is named after Zach Mulhall, father of Lucille Mulhall who was the first official 'cowgirl' to actually compete against men in rodeo events and win. The town name was changed from Alfred to Mulhall due to a petition made by Zach to the railroad shortly after the land run of 1889 because there were two towns named 'Alfred' at that time.
Most of the town was destroyed on May 3, 1999, 110 years after the town's founding, by a violent high-end F4 tornado (possibly F5 before hitting the town) which was recorded to be well over one mile wide at times. The town's water tower collapsed due to the violent winds.
