Joseph Johannis Vintcent MLC (8 November 1809 - 26 December 1873) was a member of the Legislative Council (upper house) of the Parliament of the Cape of Good Hope.

Born in The Hague, Netherlands, as the son of Lodewijk Vincent and Esther Philippine Leuliet, he became a book keeper at the cadastre in his hometown before 1836.

He was elected to the Legislative Council, where he was a keen supporter of responsible government (democratic self-rule), voluntaryism (separation of church & state), and of public works expansion.

When responsible government was attained in 1872, the new Prime Minister John Molteno offered Vintcent the position of Treasurer General.

His son Lewis Anthony Vintcent (1837-1894) became a prominent Cape Town merchant and liberal Member of the Legislative Assembly for George (1874-1894).
