Herbert Welsh (1851—1941) was a United States political reformer and worker for Indian welfare.
He was born in Philadelphia, the son of John Welsh, a prosperous merchant. He graduated at the University of Pennsylvania (1871), became known as an earnest advocate of the rights of Indians, visited the Sioux Reservation in 1882, and urged upon the public and the United States Congress education for Indian children, holding of lands in severalty by the Indians, and the extension of the civil law to their reservations. As a result of his lectures and addresses, the Indian Rights Association was founded in Philadelphia in 1883.
He was also prominent in state politics as a reformer, especially in the election of 1890. He was president of the Civil Service Reform Association of Pennsylvania, member of the executive committee of the National Civil Service Reform League, and editor of City and State, a weekly devoted to the interests of good government.
