Jan Muskata (1250 – 7 February 1320) was bishop of Kraków from 1294 to 1309.
In response Władysław had him imprisoned in 1308, which led the bishop to appeal to the Pope.
Under Wójt Albert and with Muskata's support, the Kraków burgher's revolted in 1311 against Władysław, but were suppressed.
Bishop Muskata was declared "an enemy of the Polish People" by Jakub Świnka, Archbishop of Gniezno.
