Alfred Barnes (1823 – 28 November 1901) was a British Liberal Party and later Liberal Unionist Party politician.
At the 1880 general election, he was elected as Member of Parliament for Derbyshire East. When that constituency was abolished in the Redistribution of Seats Act 1885, he was returned to the House of Commons for the new Chesterfield constituency.
When the Liberal Party split over the Irish Government Bill 1886, Barnes was re-elected at the 1886 general election as a Liberal Unionist, and held his seat until the 1892 general election. He died in Chesterfield in 1901.
