James H. Vint (January 14, 1881 - ?) was a machinist from Milwaukee, Wisconsin who served three terms as a Socialist member of the Wisconsin State Assembly.
Vint was born in Hamilton, Ontario, Canada on January 14, 1881, and came to Milwaukee in 1892, where he was educated in the Milwaukee Public Schools. He became a machinist and a member of the Machinists Union (his 1913 Wisconsin Blue Book profile says he had been a union member eleven years).
In 1910, Vint was elected to the Assembly to represent the Eighth Milwaukee County district (the 8th and 23rd wards of the City of Milwaukee). He received 1521 votes, to 1501 for Republican incumbent Fred R. Zimmerman, 143 for Democrat Harry McLogan, and 12 for Prohibitionist William Trout. He was assigned to the standing committees on agricultural exhibitions, and on express, telegraph and telephone.
In 1912, after a redistricting, he ran from the 11th Milwaukee County district, which included the 23rd ward from his old district, and the 11th ward, which had formerly constituted the 11th district and been represented by fellow Socialist Frederick Brockhausen (who was running for the Wisconsin State Senate). He won re-election, with 2242 votes to 2015 for Democrat J. F. Hefferman, 1146 for Republican L. A. Conlan, and 103 for Prohibitionist Lucia Willis; and was transferred to the committee on state affairs, and the special committee on rules.
