Sunday league football, is a term used in Britain, Ireland and Australia to describe the amateur association football competitions which take place on Sunday rather than the more usual Saturday. The term pub league may also be used, owing to the number of public houses that enter teams. Sunday league football is stereotypically seen as being of far lower quality than Saturday football and involving players who are often unfit or hungover. As a result, the term "Sunday league" can be used to describe a performance at any level of football which is seen as inept or amateurish. Despite this perception some leagues include players who also play at a high level of semi-professional football on Saturdays.

A pub is a drinking establishment licensed to serve alcoholic drinks for consumption on the premises. The term first appeared in the late 17th century, to differentiate private houses from those open to the public as alehouses, taverns and inns. Today, there is no strict definition, but CAMRA states a pub has four characteristics:is open to the public without membership or residency serves draught beer or cider without requiring food be consumed has at least one indoor area not laid out for meals allows drinks to be bought at a bar
