Pūrṇa Maitrāyanīputra (Sanskrit; Pali: Puṇṇa Mantānīputta, Chinese: 富楼那弥多罗尼子; pinyin: fùlóunàmíduōluónízǐ), also simply known as Pūrṇa (Sanskrit; Pali: Puṇṇa), was an arhat and one of the ten principal disciples of Gautama Buddha, foremost in preaching the dharma.

Puṇṇa Mantānīputta was born in Donavatthu, near Kapilavatthu, in a noble family.

Ānanda, after his first rain retreat, mentions him as a great influence in the Ānandasuttaṃ.

Puṇṇa for the first time through a conversation between the Tathāgata and a group of shakyans who praised him.

Puṇṇa uses the analogy of the relay chariots in the Rathavīnitasuttaṃ.
