- The Football League – Burnley 59 points, Manchester City 54, Bolton Wanderers 52, Liverpool 51, Newcastle United 50, Tottenham Hotspur 47
- FA Cup final – Tottenham Hotspur 1–0 Wolverhampton Wanderers at Stamford Bridge, London
- The Football League is expanded by the conversion of the Third Division (founded in 1920) into the Third Division South (D3S: 22 clubs) and the creation of the Third Division North (D3N: 20 clubs). This brings the total number of League clubs to 86. Existing league clubs in D3N are Stockport County (relegated from the Second Division) and Grimsby Town (transferred from the former Third Division). New league members in D3N are: Accrington Stanley (1921–1961), Ashington (1921–1929), Barrow (1921–1972), Chesterfield, Crewe Alexandra, Darlington, Durham City (1921–1928), Halifax Town, Hartlepool United, Lincoln City, Nelson (1921–1931), Rochdale, Southport (1921–1978), Stalybridge Celtic (1921–1923), Tranmere Rovers, Walsall, Wigan Borough (1921–1931) and Wrexham.
- Apart from Grimsby Town (now in D3N) and Crystal Palace (promoted to the Second Division), all the remaining members of the former Third Division are transferred to D3S. Two new clubs are elected to this division: Aberdare Athletic (1921–1927) and Charlton Athletic.

Events
- 2 July — boxing's first “million dollar gate” occurs when Jack Dempsey meets Georges Carpentier in a “hastily assembled outdoor arena built on a farm in Jersey City, New Jersey”. A crowd of more than 80,000 attends an event billed by its promoter Tex Rickard as the "Battle of the Century". Dempsey wins by a fourth-round knockout in a scheduled 12-round fight which is also special for its radio broadcast. It is the first-ever broadcast to a "mass audience" with ringside commentary relayed over the new radiophone to hundreds of thousands of people in the northeastern United States.[2]
- Pete “Kid” Herman regains the World Bantamweight Championship but is beaten soon afterwards by new champion Johnny Buff.

Events
- England tours Australia and becomes the first team to lose every match in a five-match Test series. In the 1921 English season, Australia emphasises the post-war superiority that it owes, in particular, to the pace duo of Jack Gregory and Ted McDonald. Having won 5–0 in Australia the previous winter, the Australians win the first three Tests of the 1921 tour and then draw the last two.
