The 1883 AAA Championships was an outdoor track and field competition organised by the Amateur Athletic Association (AAA), held on Saturday 30 June at Lillie Bridge Grounds, London, England.

Competitions commenced at three o'clock in glorious summer weather, and by the time of the 7 miles walk it was described as "blazing hot." Wellington's Light Cavalry Band played musical selections throughout the afternoon, and at the conclusion of the sports the prizes were presented by the Countess of Jersey, wife of the Earl of Jersey, President of the AAA.

1883 AAA Championships

The fourteen events on the programme were for men only, with heats and finals all held on the same day, with the exception of the 10 miles race, which was held on the following Monday, 2 July, at the same venue. The track was one-third of a mile (586 yards 2 feet) in circumference with one long straight and three bends. There were no heats in the field events, some of which had only two or three competitors. It was customary at the time for race winners only to have their performances recorded, therefore, in the tables below other competitors are shown with the distance each man was behind the man in front. Field event performances are shown in feet and inches as they were originally measured, with a conversion to metric measurement in parentheses. Conversions have been obtained using the International Metric Conversion Tables published by the International Amateur Athletics Federation in 1970.

1883 AAA Championships

There were only two foreign entries this year. Prosper Hendricks of Société Gymnastique in Brussels, Belgium, was entered in the 100 yards and 440 yards. Belgium did not have national championships until 1889 and Hendricks came to England as a complete unknown. He ran in ordinary running flats rather than "pumps" as spikes were known at the time, and although he reached the final of the 100 yards he did not distinguish himself in either event. W. S. Hart of Manhattan AC, New York, competed in the seven miles walk but was disqualified before completing two miles.

1883 AAA Championships

Notable absences included Thomas Ray (Ulverston AC), who had set a world record in the pole vault earlier in the summer and was expected to appear, and Patrick Davin of Ireland, who had entered the high jump but did not compete. Walter George (Moseley Harriers), was the reigning champion in four events, and chose to defend three of them (880 yards, 1 mile, 4 miles). In two of those races he was challenged by William Snook, known as the "little wonder", who had run fast times earlier in the summer, and their contests were predicted to be a high point of the championship.

Four events, 880 yards, 120 yards hurdles, long jump and hammer, saw championship best performances, while the 100 yards saw the championship best equalled for the fourth consecutive year. In winning the high jump John Parsons of Edinburgh University became the first Scottish athlete to clear six feet (1.83m). John Gruer's winning performance in the hammer was a world record, adding 2 ft 4 1/2in (0.72m) to the record established by Maurice Davin at these championships in 1881.

William Page Phillips (London AC) had won the 100 yards and finished second in the 440 yards in each of the three previous championships. In 1883 he did not contest the 100 yards which was won by James Cowie (London AC) who equalled the championship best of 10 1/5 seconds and also achieved the rare distinction of winning both the 100 yards and 440 yards in the same year. The only other man to achieve this is Reg Wadlsey (Highgate Harriers) in 1899. In 1923 and 1924 Eric Liddell (Edinburgh Un. AC) won both events, but only one event in each year.

In the 880 yards Thomas Bryden (Clapham Rovers FC) took the early lead and at 440 yards, reached in 56 2/5, he led by eight yards from Walter George (Moseley H.) and William Birkett (London AC). As they rounded the bend at the southern end of the stadium, referred to as the Hospital End because it was adjacent to a smallpox hospital, George spurted and Bryden was quickly overhauled. With 200 yards to go Birkett overtook Bryden and caught George, then for a few yards they ran side by side but turning into the finishing straight Birkett edged ahead and won by eight yards.
