The Football Supporters Association says league competition should be played this weekend.
All football in England has been suspended after the passing of Queen Elizabeth II.
The FSA said in a statement: "We believe football is at its finest when bringing people together at times of huge national significance – be those moments of joy or moments of mourning.
“Our view, which we shared with the football authorities, is that most supporters would have liked to go to games this weekend and pay their respect to the Queen alongside their fellow fans.
“Not everyone will agree, so there was no perfect decision for the football authorities, but many supporters will feel this was an opportunity missed for football to pay its own special tributes.
“As usual, the Football Supporters' Association will be collating advice about supporters' entitlements regarding expenses incurred relating to postponed games this weekend."
Fans could lose money as travel and hotels have already been purchased, but national rail are allowing people to claim a fee-free e-voucher for the cost of their ticket by 6pm tonight.
