The Whitechapel and St. George's by-election, 1942 was a by-election held on 8 August 1942 for the British House of Commons constituency of Whitechapel and St. George's, which covered Whitechapel, Shadwell, Wapping, and St George in the East in the Metropolitan Borough of Stepney. The by-election was caused by the death of the constituency's Labour Party Member of Parliament James Henry Hall, who had held the seat since the 1935 general election, having previously been the seat's MP between 1930 and 1931. There being no other candidates, Edwards was returned unopposed.
