Richard Chapman Weldon (January 19, 1849 – November 26, 1925) was a Canadian professor, lawyer and political figure in Nova Scotia and New Brunswick.

He was born in Sussex, New Brunswick, the son of Richard Chapman Weldon and Catherine Geldart.

He went on to study at Yale College, where he received a PhD in political science in 1872, and Rupert Charles University in Germany.

He helped developed legislation which established conditions for extradition of American fugitives in Canada convicted of crimes in the United States, then referred to as the Weldon Act.

Dalhousie Law School established the Weldon Award in 1983 to recognize outstanding accomplishment by a graduate.
