The 1949–50 FA Cup was the 69th season of the world's oldest football cup competition, the Football Association Challenge Cup, commonly known as the FA Cup. Arsenal won the competition for the third time, beating Liverpool 2–0 in the final at Wembley, through two goals from Reg Lewis.

Matches were scheduled to be played at the stadium of the team named first on the date specified for each round, which was always a Saturday. Some matches, however, might be rescheduled for other days if there were clashes with games for other competitions or the weather was inclement. If scores were level after 90 minutes had been played, a replay would take place at the stadium of the second-named team later the same week. If the replayed match was drawn further replays would be held until a winner was determined. If scores were level after 90 minutes had been played in a replay, a 30-minute period of extra time would be played.

At this stage clubs from the Football League Third Division North and South joined the 25 non-league clubs having come through the qualifying rounds. Rotherham United, Reading and A.F.C. Bournemouth, as the strongest Third Division finishers in the previous season, were given a bye to the Third Round. To make the number of matches up, non-league Yeovil Town and Bromley were given byes to this round. 34 matches were scheduled to be played on Saturday, 26 November 1949. Three were drawn and went to replays.

Entry is open to all teams who compete in the Premier League, the Football League and in steps one to five of the FA National League System, as well as selected teams in step 6. This means that clubs of all standards compete, from the largest clubs in England and Wales down to amateur village teams.

The qualification rounds and a system of byes mean that the very smallest and very biggest teams almost never meet.

Horatio Stratton "Raich" Carter (21 December 1913 – 9 October 1994) was an English sportsman who played association football for Sunderland from 1931 to 1939, for Derby County from 1945 to 1948 and for Hull City from 1948 to 1952. He also played first class cricket for Derbyshire in 1946. Later he became a football manager.

Carter was born at Hendon, Sunderland, the son of Robert Carter who played football for Port Vale, Fulham and Southampton.

Carter captained Sunderland to the Football League title in 1936, at that time the youngest man ever to have captained a First Division title-winning side. He followed that up with victory in the FA Cup final a year later, scoring the second Sunderland goal in a 3–1 win over Preston North End.

The Second World War, like many great players of his age, left him bereft of many of his peak years. Afterwards he picked up another Cup winners medal with Derby in 1946, becoming the only player to win Cup winners medals both before and after the war.

Carter was also capped 13 times for England as an inside forward.

Denis Charles Scott Compton CBE (23 May 1918 in Hendon, Middlesex – 23 April 1997 in Windsor, Berkshire) was an English cricketer who played in 78 Test matches, and a footballer. He spent the whole of his cricket career with Middlesex and most of his football career at Arsenal F.C..

In 2009 Compton was inducted into the ICC Cricket Hall of Fame.

By the late 1930s he was a leading England batsman and remained at the top of his profession for some twenty years. His dashing approach to batting and the sheer enjoyment he exuded endeared him to a generation of cricket lovers. As an all-rounder Compton was a right-hand bat and a slow left-arm Chinaman bowler.

In 1947 he thrilled a war-weary English public by breaking record after record in scoring 3816 runs; he scored 18 centuries. 753 of those runs came against the touring South Africans. This season was the summit of a glittering career that began on the ground staff at Lord's; selection for Middlesex followed in 1936 and England the following year.
