Interstate 279 (abbreviated I-279) is a north–south Interstate Highway spur that lies entirely within Allegheny County, Pennsylvania. Its southern end is at Interstate 376 at the Fort Pitt Bridge in Pittsburgh, and the north end is in Franklin Park at Interstate 79. It primarily serves at the main access route between Pittsburgh and its northern suburbs.

Interstate 279 is locally referred to as Parkway North. Its southern terminus is at Interstate 376 in downtown Pittsburgh. It runs concurrently with U.S. Route 19 Truck from its southern terminus to exit 4. (US Route 19 Truck continues on Interstate 376 west.) I-279 crosses the Fort Duquesne Bridge over the Allegheny River, providing easy access to Heinz Field and PNC Park. Interstate 579 intersects I-279, but is only accessible by southbound traffic; likewise, traffic from I-579 can only head northbound on I-279 by the Interstate 279 Interchange. I-279 features two reversible high-occupancy vehicle (HOV) lanes. The HOV lanes end at exit 5, which is an interchange with US 19. The road becomes more suburban and rural as it continues to head north. It has two additional interchanges, Bellevue/West View and Camp Horne Road. After Camp Horne Road, there are no exits until its terminus five miles later. The interstate terminates at its parent, Interstate 79. Like the interchange with I-579, this is also a partial interchange. Traffic on I-279 is only permitted to exit northbound on I-79, while only traffic heading southbound on I-79 can exit on to I-279 south.
