Upper Saucon Township is situated in the southeastern corner of Lehigh County approximately 60 miles north of Philadelphia and 80 miles east of Harrisburg. The Township is bordered on the north by Salisbury Township, on the east by Lower Saucon Township (Northampton County), on the south by the Borough of Coopersburg and Springfield Township (Bucks County), and on the west by Lower and Upper Milford Townships.

Upper Saucon has been a bedroom community for the Lehigh Valley region including the cities of Allentown, Bethlehem and Easton. The rolling hills and farmland that characterize the Township and its convenient location with easy access to PA Route 309, Interstate 78 and US Route 22 have made Upper Saucon a very attractive place to live for those wanting both a somewhat rural atmosphere but also access to metropolitan amenities.
