Benjamin Franklin “Frank” Coe (c. 1851 – September 16, 1931) was an American Old West cowboy, gunman, and member of the Lincoln County Regulators.

[citation needed] In July 1876, Coe and Ab Saunders tracked down and killed outlaw cattle rustler Nicas Meras in the Baca Canyon.

[citation needed] On July 18, 1876, both the Coe cousins, along with Doc Scurlock, Charlie Bowdre, and Saunders, broke into the Lincoln jail and grabbed an alleged horse thief, Jesus Largo, from Sheriff Saturnino Baco.

[citation needed] Fellow Regulators Charlie Bowdre, John Middleton, William H. "Billy the Kid" Bonney, and Scurlock were wounded in the shootout, while their leader, Dick Brewer, was killed.

[citation needed] After the Lincoln County War ended Coe left New Mexico, living for a time in Colorado and Nebraska.
