James "Jack" Watts (22 August 1903 – 7 July 1961) was a Conservative party politician in the United Kingdom.

He was elected at the 1959 general election as Member of Parliament (MP) for Manchester Moss Side, but died in office two years later, aged 57. Dame Agatha Christie, who was his mother Madge's sister, dedicated several books to him, including The Secret of Chimneys (1925).
