Cornelius Homan Unionist Albert Bellamy Labour The 1928 Ashton-under-Lyne by-election was held on 29 October 1928.

The election was caused by the bankruptcy of Conservative Party Member of Parliament for Ashton-under-Lyne Cornelius Homan.

Most unusually, the turnout for the by-election was higher than that for the previous general election in the seat, at 89.1% of the electorate.

The Liberals picked up a few votes, but Labour gained many more, at the expense of the Conservatives who only just avoided falling into third place.

Bellamy held the seat in the 1929 general election, but he died in 1931, precipitating another by-election, won by the Conservatives.
