The '''Topper''' is an 11 [[foot (length)|foot]] (approx. 3.3m) {{convert|43|kg|lb|abbr=on}} [[sailing dinghy]] designed by [[Ian Proctor]]. The Topper was a one-design boat until 2023 when a new version was produced, and is sailed mostly around the British Isles. It was recognised as a [[World Sailing]] Class.

The boat was previously constructed from [[polypropylene]], and now is [[Rotational molding|roto moulded]], which is popular as a racing boat or for sail training.

The class association (ITCA) organises racing events, which range from small travellers to major championships. The RYA run squads alongside the events; in these squads young sailors who are given specialist race coaching. It is sailed widely among junior sailors in the UK and Ireland and there is a growing fleet in China.
