John Calvin Chase (May 27, 1870 – January 27, 1937) was an American trade union activist and politician. He was elected to two terms as mayor of Haverhill, Massachusetts, on the Social Democratic ticket. He is considered the first socialist to be elected mayor of an American city. He later ran without success as a Socialist candidate for Governor of Massachusetts and New York, and as a Congressional candidate in Ohio and West Virginia.
