The Palatine Gate (Italian: Porta Palatina or Porte Palatine; Piedmontese: Tor Roman-e) is a Roman Age city gate located in Turin, Italy. The gate provided access through the city walls of Julia Augusta Taurinorum (modern Turin) from the North side and, as a result, it constituted the Porta Principalis Dextra (Right-Side Main Gate) of the old town.

The Palatine Gate represents the primary archaeological evidence of the city's Roman phase, and is one of the best preserved 1st-century BC Roman gateways in the world. 

Together with the ancient theatre's remains, located a short distance away, it is part of the so-called Archaeological Park, opened in 2006.

The Porta Principalis Dextra served as an access to the cardo maximus, currently identified in Via Porta Palatina and Via San Tommaso. Its impressive remains are currently visible at the center of an open area, today's Piazza Cesare Augusto.

Quite similar to the ancient Porta Decumana, built into the medieval structure of the present-day Palazzo Madama, the Palatine Gate represents an example of a typical Roman gate facing a cavaedium (quadrangular courtyard on the inside of the city walls), the remains of which are placed in front of the gate. Erected on a square base, the two angular towers are more than thirty metres high and feature a sixteen-sided structure. The central body, namely the interturrio, is about twenty metres long and is characterized by two orders of windows, the lower one composed of arch windows and the upper one made up of jack arch windows. The underlying portion features four entryways: the central ones are larger and taller and are vehicle accessible, while the two entryways to the sides are narrower and shorter and served as pedestrian passageways. The grooves along the entryways' inner walls suggest the original presence of the so-called cateractae, an alleged system of gate gratings operated from the upper floor.

On the ground near the gate is still part of the guardhouse added in the Roman period, on which one can see the furrows on the stones caused by the transit of wagons.

The pair of bronze statues depicting Augustus Caesar and Julius Caesar are not the original statues but copies from the last, radical restoration of 1934. However, they are object of discussion as they were incorrectly placed in the internal area occupied by the statio and not outside the gate, where they would possibly have more relevance.
