Side is a toponym and a common term used in geometry. As a place, it refers to a town on the Mediterranean coast of southwestern Turkey, in Antalya Province within the Manavgat district. The modern town is a popular resort known for its beaches and its proximity to ancient ruins.

The ruins of the ancient city lie on a promontory overlooking the sea and include a well-preserved Roman theater dating from the 2nd century CE and the Temple of Apollo, a hilltop sanctuary near the harbor. Archaeological remains also include substantial sections of the city walls and an ancient basilica, reflecting Greco-Roman architectural influences. The site is a focal point of heritage tourism in the region.

The ancient city of Side, located in Pamphylia on the southern coast of Anatolia, was inhabited from at least the 7th century BCE. It developed as a Greek settlement and later came under Roman rule, with a harbor that supported regional trade and a Greco-Roman architectural landscape that remains visible in the ruins today.

In geometry, a side is a straight line segment that forms part of the boundary of a polygon. A triangle has three sides, a rectangle has four, and the concept extends to more complex polygons. The term is sometimes used more loosely in everyday language to refer to the exterior boundary of a two-dimensional shape or, less commonly, to a face of a three-dimensional object.
