Brompton Bicycle is a manufacturer of folding bicycles based in Brentford, London.

The Brompton folding bicycle and accessories are the company's core product, noted for its self-supporting compact size when stored. All available models of the folding bicycle are based on the same hinged bicycle frame and 16 inch (37×349 mm) bicycle wheel tyre size. Components are added, removed, or replaced by titanium parts to form the many variations. The modular design has remained fundamentally unchanged since the original patent was filed by Andrew Ritchie in 1979, with small details being refined by continual improvement. Ritchie was awarded the 2009 Prince Philip Designers Prize for work on the bicycle. In reviews of folding bicycles, the Brompton is often the winner.

Brompton is the largest volume bicycle manufacturer in Britain, producing approximately 40,000 bicycles each year. The company also operates a Bicycle hire system.

All Brompton folding bicycle models share the same curved frame, consisting of a hinged main tube, pivoting rear triangle, fork, and hinged handle-bar stem. The main tube and stem are made of steel in all models. The rear triangle and fork are either steel or titanium, depending on model. The steel sections are joined by brazing – not welding. Wheels are 349 mm (13.7 in) rim size, carrying tyres with 16″ tread diameter. The handlebars and some peripheral components are aluminium.
