Steven Seagal: Lawman is an American reality television series that aired on A&E for its first two seasons and Reelz for its third. It stars actor, martial artist and musician Steven Seagal, performing his duties as a reserve deputy sheriff in Jefferson Parish, Louisiana (season 1–2) and Maricopa County, Arizona (season 3). It premiered on December 2, 2009.

"I've been working as an officer in Jefferson Parish for two decades under most people's radar", said Seagal in the premiere episode, "The Way of the Gun." Seagal continues "I've decided to work with A&E on this series now because I believe it's important to show the nation all the positive work being done here in Louisiana—to see the passion and commitment that comes from the Jefferson Parish Sheriff's Office in this post-Katrina environment." Seagal's current rank of Reserve Deputy Chief is largely ceremonial.
