Pennsylvania Route 309 (PA 309) is a major highway which runs for 134 miles (216 km) through Pennsylvania in the United States. The route runs from the interchange between PA 611 and Cheltenham Avenue on the border of Philadelphia and Cheltenham Township north to an intersection with PA 29 in Bowman Creek, a village in Monroe Township, Wyoming County. It connects Philadelphia and its northern suburbs to Allentown, Hazleton, and Wilkes-Barre. A limited-access highway portion of PA 309 in the Wilkes-Barre area is known as the North Cross Valley Expressway. A limited-access highway portion of PA 309 in Montgomery County is known as the Fort Washington Expressway. PA 309 parallels the newer Interstates 476 and 81 for much of its length.

PA 309 begins at an interchange between PA 611 and Cheltenham Avenue on the border between Cheltenham Township in Montgomery County to the north and the East Oak Lane section of the city of Philadelphia to the south. From this interchange, the route heads northwest on four-lane divided Cheltenham Avenue along the border between Cheltenham Township and Philadelphia. A short distance past the PA 611 interchange, the road comes to an intersection with the northern terminus of Broad Street. PA 309 continues northwest as a four-lane undivided road through residential and business areas, running between suburban areas to the northeast and urban areas to the southwest. The road crosses Washington Lane and passes to the south of the Cheltenham Square Mall before it comes to an intersection with Ogontz Avenue north of the West Oak Lane neighborhood of Philadelphia. At this point, PA 309 turns north-northwest onto four-lane divided Ogontz Avenue and fully enters Cheltenham Township in Montgomery County, passing businesses as it heads to the west of the mall. The route intersects Limekiln Pike and assumes that name, passing near residential development in the community of Cedarbrook.
