Archibald Yell was an American politician and lawyer who served as the U.S. representative from Arkansas from 1836 to 1839, and 1845 to 1846. He was the second governor of Arkansas, serving from 1840 to 1844. Yell was killed in action during the Mexican-American War at the Battle of Buena Vista on February 23, 1847.

The Battle of Buena Vista, known as the Battle of La Angostura in Mexico, and sometimes as Battle of Buena Vista/La Angostura, was a battle of the Mexican–American War. It was fought between US forces, largely volunteers, under General Zachary Taylor, and the much larger Mexican Army under General Antonio López de Santa Anna. It took place near Buena Vista, a village in the state of Coahuila, about 12 km (7.5 mi) south of Saltillo, Mexico. La Angostura was the local name for the site. The outcome of the battle was ambiguous, with both sides claiming victory. Santa Anna's forces withdrew with war trophies of cannons and flags and left the field to the surprised U.S. forces, who had expected there to be another day of hard fighting.
