Mulino was named by C.F. Howard in 1882, and the name was corruption of the Spanish word molino, which means mill. Postal authorties would not accept the name Molino because it was too much like the nearby Molalla. Richard R. Howard, father of C.F. Howard, erected a flour mill at Mulino in 1851, and the place was known as Howards Mill. The mill building, still standing in 2003, although enlarged and altered, is probably the oldest surviving industrial building in Oregon. Mulino post officewas established March 21, 1882, with James G. Foster as the first postmaster.
