Eric Geddes Conservative George Newton Conservative The 1922 Cambridge by-election was a by-election held on 16 March 1922 for the British House of Commons constituency of Cambridge.

The by-election was caused by the resignation on 7 November 1921 of the town's Conservative Party Member of Parliament (MP) Sir Eric Geddes, who had held the seat since 1917, and had come under criticism as Minister of Transport for the scale of nationalisation he had overseen, and over charges of departmental inefficiency.

He chose to resign as both cabinet minister and MP.

The result was a comfortable victory for the new Conservative candidate Sir George Newton, who held the seat until his elevation to the peerage in 1934 as Baron Eltisley.

Of the two unsuccessful candidates, Hugh Dalton was a Cambridge-educated LSE lecturer in economics who went on to be an MP from 1924, and became Labour's Chancellor under Clement Attlee; and Sydney Cope Morgan was a Cambridge-educated barrister who went on to contest the seat again for the Liberals with an increased vote at each of the next two general elections.
