Captain Ewen Cameron (1811 – April 26, 1843) was an officer in the Army of the Republic of Texas, who participated in the ill-fated Mier Expedition.

The 17 Texan prisoners who drew black beans were executed at dusk by a Mexican firing squad.

Yet he had earned the hostility of Mexican Colonel Antonio Canales Rosillo for his role in his embarrassing defeat in the Battle at Fort of Lipantitlán, Texas, in July 1842, and for Cameron's role in leading an escape attempt.

Colonel Canales urged the Mexican dictator Antonio López de Santa Anna to have Cameron executed.

Cameron was shot by a firing squad at Perote Prison in the state of Veracruz, the next morning, April 26, 1843.
