Herbert Welsh (1851–1941) was a United States political reformer and worker for the welfare of the indigenous peoples of North America.

Welsh became known as an earnest advocate for the rights of Native Americans, a calling triggered by a visit to the Sioux Reservation in 1882.

In January 1894, Welsh became chair of the committee to plan the National Municipal League at a meeting of civil reformers held in Philadelphia, including Teddy Roosevelt, Louis Brandeis, and Frederick Law Olmsted.

Sunapee in New Hampshire near his summer home, Welsh led the effort to raise funds to conserve the mountain lands.
