Hendrick Christiaensen (15??? - 1616) was a Dutch explorer who was involved in the earlier exploration of what became present day New York City.
In 1611, Christiaensen paid two visits to Manhattan, including one with fellow explorer Adriaen Block. Upon his return to the Netherlands following the second of his trips, he brought back with him two young Indians, who were the sons of a local sachem. The Dutch were fascinated with the boys, and they eventually earned the names Orson and Valentine.
By 1613, Christiaensen was captain of the vessel Fortuyn. He again returned to Manhattan, and with Adrien Block, he created the first map of the region that showed Manhattan and Long Island as seperate geographical entites.
In 1616, Hendrick Christiaensen was murded by his adoptive son Orson near present Albany,
