The Fourth Test of the 1948 Ashes series was one of five Tests in a cricket series between Australia and England. The match was played at Headingley Stadium at Leeds from 22 to 27 July with a rest day on 25 July. Australia won the match by seven wickets to take an unassailable 3–0 series lead. In successfully chasing a target of 404, they set a new world record for the highest victorious runchase in Test history.
Needing to win the match to prevent an Australian series victory, England captain Norman Yardley won the toss and elected to bat. England continued to rearrange their team, making three changes in an attempt to find a combination that could challenge Australia, which made two changes forced by injury. Unlike the preceding Tests, England's openers were able to withstand the Australian new ball attack, and the partnership of Len Hutton and Cyril Washbrook put on 168 for the opening stand. Washbrook fell for 143 in the last over of the day, but England clearly had the better of the play, ending at 268/2 by stumps. Australia's bowlers were heavily criticised for their performance, which was seen as lethargic. The next day, England continued to amass runs, with Australia appearing unthreatening and unable to dislodge Bill Edrich and nightwatchman Alec Bedser, who batted until mid-afternoon. Bedser and Edrich then fell in quick succession for 79 and 111 respectively as England then collapsed and lost 8/73 to be all out for 496 late in the day. The hosts were heavily criticised for the collapse, which was largely due to unforced errors. Among the Australian bowlers, the wickets were shared. Australia then reached 63/1 in reply at stumps on day two.
