Alexandra Palace railway station (Muswell Hill branch) is a former station in the grounds of Alexandra Palace in the Muswell Hill area of north London. It is one of a number of stations to have held the name at various times and should not be confused with the current holder, Alexandra Palace Station on the First Capital Connect line to the east.
The station was the terminus of a short branch line from Highgate Station. The previous station on the line was Muswell Hill Station. The station was located immediately adjacent to the north side of the Palace buildings. Nothing remains of the tracks or island platform today which have been removed and covered with car park but the small station building, known locally as CUFOS (Community Use For Old Station), remains.
