Beck Mountain is a summit in St. Francois County, Missouri, southeast of Farmington. Rising to 1,050 feet, it stands near the St. Francis River on its southwest side, with Rickus Hill to the southeast. The mountain was named for Andrew Beck, a pioneer citizen, preserving the memory of an early settler in this part of southeastern Missouri. Though it is not a major landmark in a larger range, it remains a named local height whose significance lies in its connection to the area's early settlement.
