Melville Reeves Hopewell (March 27, 1845 – May 2, 1911) was a Nebraska lawyer and Republican politician who served as the state's 12th lieutenant governor from 1907 to 1911.

After his mother died in 1854, the family returned to Indiana, where his father remarried, and then moved to Kansas, followed by Gentry County, Missouri.

Hopewell served in the Missouri Mounted Militia from 1863 to 1864.

He founded the first bank in Burt County, Nebraska, in 1873.

In 1887, Nebraska Governor Thayer appointed Hopewell as a district judge, which he served as until 1896, at which point he resumed his practice of law.
