A lay disciple of Sāvatthi. He was a Non-returner according to the Jātaka account (J.i.381 f ) and a Once-returner according to the Dhammapada Commentary (DhA.i.380 f ).

Once, when listening to the Buddha’s teaching, he failed to notice and do reverence to the king, Pasenadi, who arrived during the discourse. Later, when summoned to the king’s palace, he went with every sign of respect and paid obeisance to the king. When asked why he had not so behaved on the previous occasion, Chattapāṇi replied that such an action would have been discourteous to the Buddha. Thereupon Pasenadi asked him to act as instructor in the Dhamma to the women of the palace, but he refused the invitation, deeming that such a course would be unseemly and unwise. The task was therefore given to Ānanda. DhA.i.380 f; cp. Vin.iv.157. The story is also found in J.i.381 f, with several variations in detail. There we are told that the Buddha, seeing that the king was displeased, made special mention to him of Chattapāṇi’s attainments.
