Pyanchi II (Burmese: ပျံချီငယ်, pronounced [pjàɴtɕʰì ŋɛ̀]) was viceroy of Toungoo (Taungoo) from 1376 to 1379/80.
He came to power three months after his father Pyanchi I was assassinated near Prome (Pyay) by the pro-Ava forces in 1375.
In the ensuing power struggle at Toungoo, in which the Hanthawaddy army led by Ma Sein had seized the city of Toungoo, he and brother-in-law Sokkate managed to oust Ma Sein.
He is said to have spent much of his time as a playboy.
He was assassinated in 1379/80 by Sokkate, who seized the office.
