Porta delle Lame or Porta Lame was a gate or portal of the former outer medieval walls of the city of Bologna, Italy. It is located at the end of Via Lame, where it meets via Zanardi.

Originally, a gate was built in the medieval walls in 1334, and had two drawbridges, one for carriages, and the other for pedestrians. The gate was rebuilt in 1677 in a Baroque style by the architect Agostino Barelli. The most recent restoration was 2007–2009. Surrounding the gate are bronze statues depicting partisans who fought at this site on November 7, 1944.
