William George McConnell (3 March 1889 – 6 January 1966) was an Irish footballer in the years before World War I who was part of the first Ireland team to win the British Home Championship outright in 1913–14.

The following year, installed in his favoured right-back role, he played in a 2–1 victory over England at Windsor Park – Ireland's first success against their largest neighbours.

During the 1–1 draw against Scotland in the game to secure the championship, McConnell suffered an injury was forced to go into goal for Ireland after Fred McKee was also hurt and had to leave the field.

In a hard-fought and crowd-troubled match at Dalymount Park, his club home ground, McConnell put in an energetic performance, and only the mis-firing forward-line denied the Irish a more favourable result.

He was part of a squad which contained such notable footballers as Bill Lacey, Val Harris and Billy Gillespie but the outbreak of War and the suspension of international games meant that Ireland were not able to build on the success of 1914.
