Prince Street is a street in the North End of Boston, Massachusetts, United States. It runs for around 0.32 mi, from Causeway Street and Commercial Street in the northwest to North Square at Garden Court Street in the southeast. It is one-way, southbound, except for the block between Hanover Street and Garden Court Street, which is northbound. Prince Street was originally known as Black Horse Lane. Causeway Street, meanwhile, was formerly Endicott Street.

The Boston Draft Riot of July 14, 1863, began on Prince Street.

In the 20th century, the street became notable as the headquarters of the Angiulo brothers, the leading Italian-American crime group in Boston from the 1960s until the mid-1980s. They were based at 98 Prince Street (known as the Dog House), at the corner of Thacher Street in Gaetano Iovanni Square (U.S. Army staff sergeant Iovanni, of 138 Prince Street, was killed in action during World War II). The building had a real-estate agency as a front. Giovanni and Cesare Angiulo, the brothers' parents, lived across the street at number 95. In January 1981, FBI agents placed bugs in Angiulo headquarters for over three months and listened to their discussions about murder.
