Sarnath or Sārnātha (also Mrigadava, Migadāya, Rishipattana, Isipatana) is the deer park where Gautama Buddha first taught the Dharma, and where the Buddhist Sangha came into existence through the enlightenment of Kondanna. Sarnath is located 13 kilometres north-east of Varanasi, in Uttar Pradesh, India.

The Buddha went from Bodhgaya to Sarnath about 5 weeks after his enlightenment. Before Gautama (the Buddha-to-be) attained enlightenment, he gave up his austere penances and his friends, the Pañcavaggiya monks, left him and went to Isipatana.
After attaining Enlightenment the Buddha, leaving Uruvela, travelled to the Isipatana to join and teach them. He went to them because, using his spiritual powers, he had seen that his five former companions would be able to understand Dharma quickly. While travelling to Sarnath, Gautama Buddha had to cross the Ganges. Having no money with which to pay the ferryman, he crossed the Ganges through the air. When King Bimbisāra heard of this, he abolished the toll for ascetics. When Gautama Buddha found his five former companions, he taught them, they understood and as a result they also became enlightened. At that time the Sangha, the community of the enlightened ones, was founded. The sermon Buddha gave to the five monks was his first sermon, called the Dhammacakkappavattana Sutta. It was given on the full-moon day of Asalha. Buddha subsequently also spent his first rainy season at Sarnath at the Mulagandhakuti. The Sangha had grown to 60 in number (after Yasa and his friends had become monks), and Buddha sent them out in all directions to travel alone and teach the Dharma. All 60 monks were Arahants.
