Le Than Bwa (Burmese: လယ်သံဘွား, Burmese pronunciation: [lɛ̀ ðàɴ bwá]; also known as Hsan Hpa, died 1459/60) was sawbwa (ruler) of Onbaung from the 1420s to 1459/60. Initially a vassal of Ava, the sawbwa kept his small Shan-speaking state independent from 1426 to 1444. He is known in Burmese history for his 1425 assassination of King Thihathu of Ava.
