Interstate 579 (abbreviated I-579) is a north-south Interstate Highway auxiliary route. At 1.57 miles long, it is short but not the shortest Interstate. It lies entirely within Pittsburgh, Pennsylvania. Interstate 579 is also known as the Crosstown Boulevard.

The northern terminus of I-579 is at Interstate 279 on the Veterans Bridge and the Interstate 279 Interchange, while the southern terminus splits into the Liberty Bridge and Boulevard of the Allies, which connects to eastbound Interstate 376. The intersection of I-579 and I-279 is in one direction only; northbound traffic on I-579 can proceed only northbound on I-279, while only southbound traffic on I-279 can exit onto I-579.

I-579 running through downtown Pittsburgh

I-579 allows Liberty Bridge traffic easy access to I-279, and I-279 southbound traffic easier access to Mellon Arena, downtown, and eastern regions of the city, while I-279 southbound continues to Heinz Field, PNC Park, and Pittsburgh International Airport.

Construction on Interstate 579 was not completed until 1989, with the opening of the Veterans Bridge, and the opening of Interstate 579 was concurrent with the opening of an extension of Interstate 279 into the North Hills region of the Pittsburgh metropolitan area.

In the past, this was Interstate 479 and Interstate 876 prior to becoming Interstate 579.
