Alemany Boulevard is a northeast–southwest street in San Francisco, California, United States.

It starts at Bayshore Boulevard near the Alemany Maze (the intersection of Interstate 280 and U.S. 101).

The eastbound and westbound lanes split beneath the interchange, allowing for access ramps to US-101 from the middle.

Between Brotherhood Boulevard and San Jose Avenue, Alemany runs one-way eastbound, with westbound traffic crossing under I-280 and through Sagamore Street, meeting up with Alemany again.

Alemany, who in 1840 completed his studies in sacred theology in Rome at the College of St. Thomas, the future Pontifical University of Saint Thomas Aquinas, Angelicum, was consecrated Bishop of Monterey in California at Rome on June 30, 1850.
