The 1906 Yorkshire Cup was the second in the Rugby Football League club tournament's history. It was a knock-out competition between (mainly professional) rugby league clubs from the English 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)
1906 was the second occasion on which the Yorkshire Cup competition had been held.
This year there were two new clubs to contest the final.
Brighouse Rangers, Castleford (1896) and Normanton left the league and the three non league clubs from last season were not invited, but they were replaced by junior/amateur club New Blackpool. This resulted in an overall decrease of five clubs, leaving a total of fifteen entrants.
This, in turn, resulted in one bye in the first round.
Pontefract resigned after 8 league matches and their record was expunged, but by this time, they had played (and lost) in this competition.
^New Blackpool is/was a junior/amateur club (possibly from the Leeds area)
^Belle Vue is the home ground of Wakefield Trinity with a capacity of approximately 12,500. The record attendance was 37,906 on the 21 March 1936 in the Challenge Cup semi-final between Leeds and Huddersfield
