The 2003 Football Fans Census revealed that no other team's supporters considered York to be among their club's main rivals.[149] Traditionally, York's two main rivalries have been with Hull City and Scarborough.[149] While York fans saw Hull as their main rival, this was not reciprocated by the East Yorkshire club, who saw Leeds United as their main rival.[149] York also had a rivalry with Halifax Town and they were the team most local to York when the two played in the Conference.[150] A rivalry with Luton Town developed during the club's final years in the Conference as both clubs met regularly in crucial matches, accompanied by a series of incidents involving crowd trouble, contentious transfers, and complaints about the behaviour of directors.[151][152][153][154]
