Hosensack (HOE-zen-sak) is an unincorporated community in Lower Milford Township in Lehigh County, Pennsylvania.
Zionsville is two miles to the north and Hosensack residents use its zip code of 18092, except for a very small number on Mill Hill who use the East Greenville zip code of 18041.
During the mid-1730s, Kings Highway was surveyed and settlement began in the Hosensack Valley.
A group of German travelers who spent a night in the valley were reported as saying, "es war so dunkel wie in einem Hosensack", meaning "it was as dark as in a pants pocket."
