State Route 62 (SR 62), also known as Monsanto Road, is a 2.443-mile-long (3.932 km) state highway near Guntersville in Marshall County.

The highway heads east from lakeside homes and marinas along Lake Guntersville to SR 227 near Guntersville.

SR 62 previously provided access to a (now abandoned) Monsanto plant, for which it was built and named.

At its western end was the entrance to the now abandoned Monsanto production facility, which was the reason for SR 62 being built.

Between 1964 and 1993, SR 62 was assigned to the highway connecting Ohatchee and Alexandria in Calhoun County.
