Pennsylvania Route 737 (Route 737) is a state highway in Berks County, Pennsylvania. The route runs from U.S. Route 222 in Kutztown north to Pennsylvania Route 143 in Albany Township. Route 737 heads north from an interchange with the U.S. Route 222 Kutztown Bypass north of Kutztown on Krumsville Road. It continues north through a small part of Maxatawny Township into Greenwich Township. The road features an interchange with Interstate 78/U.S. Route 22 near the village of Krumsville. Route 737 then heads northwest into Albany Township where it ends Route 143 near the village of Kempton.

Route 737 was assigned to a formerly un-designated local road between Kutztown and Kempton in 1962. Around that time, U.S. Route 222 served as the southern terminus in downtown Kutztown. When the Kutztown Bypass was constructed in the 1970s, U.S. Route 222 was realigned off of Main Street in Kutztown and onto the bypass. The road, at that point, ended at the now locally-maintained Main Street until 1978, when the designation was truncated. Since then, the route has remained virtually untouched in alignment.
