Joseph Trevor Park (12 December 1927 – 6 April 1995) was a British lecturer and politician. He was a Labour Party Member of Parliament during Harold Wilson's government in the 1960s, a government which he regarded as unhelpful to the interests of Labour voters.
Park was born in Lancashire, the son of textile workers. He won a scholarship to Bury Grammar School and to Manchester University, and went into teaching in Bacup and Rawtenstall Grammar School on leaving university. From an early age he became interested in politics and made no secret of his desire for a political career.
At the 1955 general election, Park fought Altrincham and Sale (a safe Conservative seat). His political involvement was unpopular with his employer, and soon after he left to become a lecturer for the Workers Educational Association. This body, which worked with the Trades Unions, looked kindly on members who wanted to be involved in politics.
Park made a strong speech at the Labour Party conference in 1958, which was highly critical of the leadership of Hugh Gaitskell. In the general election the following year, he stood in another safe Conservative seat, this time Darwen. Park's attendance at the Trade Union Congress and successive Labour Party conferences, coupled with his ability to impress with speeches, led to a degree of popularity. Meanwhile, his academic career flourished, with an appointment as a lecturer in the Department for Extramural Studies at the University of Sheffield
