Holland Brook is a tributary of the South Branch Raritan River in Hunterdon and Somerset Counties, New Jersey in the United States.

Holland Brook flows through Readington and Branchburg. It is the last tributary of the South Branch Raritan River before it combines with the North Branch Raritan River.

The brook is over seven miles in length running from its headwaters near Cushetunk Mountain,^[1] a plutonic intrusion of igneous rock surrounding Round Valley Reservoir, to its convergence with the South Branch Raritan River near Studdiford Drive in Branchburg. The brook is ten to twenty feet across most of its length. It changes over 300 feet in elevation from its headwaters to its convergence with the Raritan River.

Holland Brook was originally named Holland's Brook for Thomas Holland of Piscataway, who was married to Winifred Pound. Thomas Holland was a descendant of the translator Philemon Holland.^[2] Holland was an early property owner along the brook, although he never resided there. The recorded Lenape name for the Brook was Amanmechunk.^[3] This word in the Unami dialect meant large creek.
