P'yà Ânggang County is a kun, or county, in Kangwà Ân province, North Korea. It borders Sep'o to the north, Ch'à Ârwà Ân to the south, Ich'à Ân to the west, and Kimhwa to the east.
A portion of the county is occupied by the Ryongam wetlands, which also cross into Ch'à Ârwà Ân. Most of the county's terrain is mountainous, although there a few small expanses of level ground. The Kwangju and Majà Âllyà Âng mountains pass through P'yà Ânggang. The region is prone to heavy rains.
The P'yà Ânggang area was known as Puyang hyà Ân during the Koguryà  period, and as Kangp'yà Âng (ê°ÂÃÂÂ) under Silla. In the Koryà  Dynasty, it was included in Tongju (ëÂÂ주); in the Chosà Ân dynasty, it took its modern name.
