The Temple of Dionysus in Side is a partially preserved Roman-era temple located near the ancient theatre. It was dedicated to Dionysus, the Greek god of wine, theatre, and festivity. Built in the 2nd century AD, the temple likely played a key role in cultural and theatrical life, as its location next to the theatre suggests a connection to performances and public celebrations. Though only a few structural elements remain today, the temple site is an important part of Side's religious and social history.
