B.R.B. Engineering Co. was a British manufacturer based in Hornsey, London, that operated in the early 20th century. Founded in 1921, the company specialized in the production of cyclecars, a type of lightweight automobile that was popular during that era.

The primary model produced by B.R.B. featured an 8 horsepower V-twin JAP engine, which was known for its reliability and performance. The vehicle utilized a friction transmission system and chain drive, characteristic of many cyclecars of the time. The company offered a two-seater model priced at £200, although production numbers were limited, resulting in very few units being made.

B.R.B. Engineering Co. represents a small chapter in the history of British automotive manufacturing, reflecting the innovation and experimentation that characterized the cyclecar movement in the early 20th century.
