Richmond Mumford Pearson, Jr. (January 26, 1852 – September 12, 1923) was an American diplomat and member of the U.S. House of Representatives from North Carolina.

The same year he was appointed United States consul to Verviers and Liège, Belgium, which he resigned in 1877.

When he ran for re-election in 1898, he was initially declared the loser, and William T. Crawford the winner.

But he successfully contested the election and was seated for the last half of the Fifty-sixth Congress (May 10, 1900 to March 1901).

He retired from the diplomatic service in 1909, and lived most of his later life at his home in Asheville, North Carolina, called "Richmond Hill" (the same name as his father's home in Yadkin County).
