Jan Jansen Bleecker (July 9, 1641 — November 21, 1732) was a colonial era merchant and political figure who served as Mayor of Albany, New York.

[1] Jan Jansen Bleecker was born in Meppel, Drenthe, Netherlands on July 9, 1641, and was the first of his family to come to North America.

[6] When Jacob Leisler led a rebellion against British authority in New York from 1689 to 1691, Albany was a stronghold of anti-Leisler opposition.

Bleecker served as a member of the Albany convention that attempted to convince Leisler to allow British military supplies to move north from New York City in anticipation of a French attack from Canada.

[15] In addition, Harmanus Bleecker (1779–1849), another descendant, served in the United States House of Representatives and as Chargé d'Affaires in the Netherlands.
