The Sawkill mill was a sawmill and slave quarters established by the Dutch West India Company in 1626, as part of the construction of New Netherland, a colonial province in North America. The mill was located at the mouth of the Sawkill, a stream that originated in what is now Central Park in New York City, and flowed into the East River. The slaves, who were mostly men, cut wood for the new colony and floated the logs which were guided by boat to New Amsterdam, the capital of New Netherland. The mill and the slave quarters are depicted on The Manatus map of 1639, the oldest map of Manhattan Island, which shows the Saw-Kill as a slave settlement of the Dutch West India Company, not as a mill site. This implies that by 1639, the Saw-Kill mill had reduced its wood-cutting activities.

The Sawkill or Saw-kill was the largest hydrological network on Manhattan island in New York City before the Dutch colony of New Netherland was founded in 1624. This 44,980-foot-long (13,710 m) stream began "within four blocks of the Hudson River":A rill flowing east from the rocky ridge overlooking Bloomingdale Village, which rose near Ninth Avenue and 85th Street, flowed in a southerly direction through Manhattan Square, where it spread into a little pond, and then turned east, crossing Central Park to Fifth Avenue, receiving three tributaries within its limits, two from the north and one from the south. At 75th Street near Third Avenue it was joined by another stream. Near this junction the old Boston Post Road crossed it, and then from this point, the stream ran due east to its outlet near the foot of 75th Street
