The Labour Party Constitution is the rulebook of the UK Labour Party.

The original Labour Party constitution was drafted by Sidney Webb, a founder of the London School of Economics and Fabian Society. The objects of the Labour Party were as follows:

1. To organise and maintain in parliament and in the country a political Labour Party

2. To cooperate with the General Council of the Trades Union Congress, or other kindred organisations, in joint political or other action in harmony with the party constitution and standing orders.

3. To give effect as far as possible to the principles from time to time approved by the party conference.

4. To secure for the workers by hand or by brain the full fruits of their industry and the most equitable distribution thereof that may be possible upon the basis of the common ownership of the means of production, distribution, and exchange, and the best obtainable system of popular administration and control of each industry or service.

5. Generally to promote the political, social and economic emancipation of the people, and more particularly of those who depend directly upon their own exertions by hand or by brain for the means of life. ^{[citation needed]}

In 1960, Hugh Gaitskill attempted amendments to the constitution, including change of clause IV, but was voted down. However two further points were added.
