James Roberts (21 February 1878 – 4 February 1967) was a New Zealand trade unionist, politician and was president of the Labour Party from 1937 to 1950.
He was called 'Big Jim' and 'the uncrowned King of New Zealand' in recognition of the considerable influence he wielded during the period of the First Labour Government over policy creation and implementation.
