David William Ernest Webster (20 October 1923 – 7 January 1969) was a British Conservative Party politician.
Born in Arbroath, Scotland, Webster was a stockbroker before entering Parliament. He contested Bristol North East in 1955. He was elected as Member of Parliament (MP) for Weston-super-Mare in the 1958 by-election after the death of Sir Ian Leslie Orr-Ewing.
He was returned at three subsequent general elections, before his death in 1969, following injuries sustained in a skiing accident in Austria. He was 45 years old. The consequent by-election for his seat was won by the Conservative candidate, Jerry Wiggin.
