The Rugby League Yorkshire Cup competition was a knock-out competition between (mainly professional) rugby league clubs from the county of Yorkshire. The actual area was at times increased to encompass other teams from outside the county such as Newcastle, Mansfield, Coventry, and even London (in the form of Acton & Willesden.
The Rugby League season always (until the onset of "Summer Rugby" in 1996) ran from around August-time through to around May-time and this competition always took place early in the season, in the Autumn, with the final taking place in (or just before) December (The only exception to this was when disruption of the fixture list was caused during, and immediately after, the two World Wars)
