The Temple of Hephaestus, also known as the Hephaisteion, is an ancient Greek temple located on the northwest side of the Ancient Agora of Athens. It was built in the 5th century BCE and is considered one of the best-preserved ancient Greek temples in the world.

The Temple of Hephaestus is a Doric-style temple made of marble and limestone. It features 34 columns and a rectangular floor plan with a central cella (sanctuary) surrounded by a peristyle (a colonnade that surrounds the temple).
