Corner is located in Jefferson County at the intersection of Jefferson County, Walker County, and Blount County, hence the name. The community is about 6 miles west of Warrior. Much of it lies upon York Mountain, and as far away as Birmingham may be seen on clear days. Residents of Corner carry either Dora (648) or Warrior (647, 590) telephone prefixes and Dora, Warrior, or Empire ZIP codes. Territory is often defined by school zone, and the exact boundary is unclear between Corner and neighboring communities such as Bagley. Corner High School, with an enrollment of about 1,000 in grades K-12, is the area's focal point.
Corner Middle School and Corner Elementary School are located at the intersection of Bagley (Mayfield) Road and Corner School Road. Corner High School, previously located at the same site as the middle and elementary schools, moved in 2010 to a new facility three miles (5 km) to the west on Warrior-Jasper Road. The school competes in Class 4A of the Alabama High School Athletic Association. The mascot is the yellow jacket. Their rivals are the Oak Grove Tigers, Sumiton Christian Eagles, and the Hayden Wildcats.
Coach Zac Willis is the head football coach at Corner. It has an award winning marching band, led by director Rick Coggin and assistant director Cory Wills. The band participated the BOA Grand Nationals Championships during November 11–14, 2009 in Indianapolis, Indiana. It is also home to a notable theatre troupe, under directors Michael Putman and Debra Reeser.
