Overton is a community that is part of the unincorporated town of Moapa Valley in Clark County, Nevada.

Overton was originally settled in 1869 by members of the Church of Jesus Christ of Latter-day Saints, led by Helaman Pratt.

In the 1930s, the town of St. Thomas was submerged by water as Lake Mead was being filled, and the majority of its population relocated to Overton.

[8] Nevada State Route 169 connects Overton with Interstate 15 (exit 93) in the north and Lake Mead National Recreation Area in the south.

Overton is located on the former St. Thomas branch of Los Angeles and Salt Lake Railroad which runs along the Moapa Valley, from north to south.

The construction of the branch started in 1911 from Moapa station, which lies on the main line between Salt Lake City and Las Vegas.
