Fer was sent off by referee Anthony Taylor in the second half of Saturday's 0-0 draw for a trip on Helder Costa.
A statement on the club's website said: "Swansea City have lodged an appeal against Leroy Fer's sending-off at Wolves on Saturday.
"The midfielder was shown a straight red card in the 67th minute of the Emirates FA Cup tie for a foul on Helder Costa which was deemed by referee Anthony Taylor to constitute violent conduct."
