4. c. 129) was an Act of Parliament of the United Kingdom, which prohibited trade unions from attempting to collectively bargain for better terms and conditions at work, with the exception of increased wages and better working hours and suppressed the right to strike.

Accordingly, the Combinations of Workmen Act 1825 was passed to reimpose criminal sanctions for picketing and other methods of persuading workers not to work.

The 1825 act was recommended for amendment by the majority report of the Eleventh and Final Report of the Royal Commissioners appointed to Inquire into the Organisation and Rules of Trade Unions and Other Associations in 1869.
