Monkinie [mɔŋˈkiɲɛ], (Lithuanian: Mankynė), is a village in the administrative district of Gmina Nowinka, within Augustów County, Podlaskie Voivodeship, in north-eastern Poland. It lies approximately 9 kilometres (6 mi) north-east of Nowinka, 17 km (11 mi) north-east of Augustów, and 97 km (60 mi) north of the regional capital Białystok.

During the German occupation of Poland (World War II), the Germans arrested multiple members of the local Polish resistance movement, including local parish priest Bolesław Cieciuchowski, and then murdered 12 resistance members near Suwałki on September 29, 1943 (see Nazi crimes against the Polish nation). The priest was then buried by his brother and local parishioners in Monkinie.
