Allendale Mill is a historic mill at 494 Woonasquatucket Avenue in North Providence, Rhode Island, on the banks of the Woonasquatucket River. The oldest buildings in the mill complex were built in 1822 by John Holden Greene for Zachariah Allen. The mill had various fire safety devices that were advanced for the time, including "heavy fire doors, sprinkler system, rotary fire pump, and copper-riveted fire hose to be used in American textile mills. In addition, Allen built a heavy fire wall separating the picker room (filled with highly flammable cotton fibers) from the rest of the mill and set the roofshingles in mortar." The second building, also of 1822, was a company store building. It still stands next to the mill, facing Woonasquatucket Avenue.
