Peter Hardy, Baron Hardy of Wath, DL (16 July 1931 – 16 December 2003) was a British Labour politician.
The son of a Wath-upon-Dearne miner, Hardy was educated at Wath upon Dearne Grammar School. He trained as a teacher at Westminster College, London, and gained a degree in Curricular Studies at Sheffield University before rising to be head of English at Mexborough County Secondary School.
While a local councillor, he stood unsuccessfully as a parliamentary candidate in several safe Conservative seats - in 1964 he contested Scarborough and Whitby, and in 1966 he fought Sheffield Hallam.
He entered parliament in 1970 for the Rother Valley constituency. In 1983, when constituency boundaries were re-organised, he moved with a part of his old Rother Valley constituency to the re-formed Wentworth constituency, for which he was Member of Parliament (MP) until retirement from the House of Commons in 1997.
Never keen on the pursuit of high office, he was parliamentary private secretary to Tony Crosland and David Owen. To his constituents he was a popular and hard-working constituency MP. This was reflected in the fact that, despite being identified with the right wing of the Labour party, in 1981 he survived a National Union of Mineworkers-directed attempt to force the local party in his mining constituency to deselect him as its parliamentary candidate in favour of a more left-wing candidate.
