Jetavana was one of the most famous of the Buddhist monasteries or viharas in India. It was the second vihara donated to Gautama Buddha after the Veluvana in Rajgir.
Jetavana is located just outside the old city of Savatthi. There was also an important vihara named Jetavana in Sri Lanka.
Jetavana was the place where the Buddha gave the majority of his teachings and discourses, having passed at Jetavana nineteen out of 45 vassas, more than in any other monastery. It is said that after the Migāramātupāsāda, a second vihara erected at Pubbarama, close to Savatthi, came into being, the Buddha would dwell alternately in Jetavana and Migāramātupāsāda, often spending the day in one and the night in the other (SNA.i.336).
