Taṇhaṅkara or Taṇhaṅkara Buddha is the first of the twenty-seven Buddhas who preceded the historical Gotama Buddha and the earliest known Buddha.[1] He was also the first Buddha of the Sāramaṇḍa kalpa.
In the Buddhavamsa of the Pali canon, he is briefly mentioned as:
Innumerable aeons ago, Taṇhaṅkara Buddha, Medhaṅkara Buddha, Saraṇaṅkara Buddha and Dīpaṃkara Buddha were born in the Sāramaṇḍa kalpa.[2]
