John Cumming Macdona (1836 – 4 May 1907) was a British cleric, barrister, and Conservative MP for Rotherhithe.

Educated at Trinity College, Dublin, he was ordained in the Church of England and was Rector of Cheadle, Cheshire until 1873.

He later gave up the clerical life for a career as a politician and barrister, being called to the bar by the Middle Temple in 1889.

He was elected for Rotherhithe as a Conservative in 1892, held the seat in 1895 and 1900, but lost it to the Liberals in the landslide of 1906.
