Robin Herd (born 23 March 1939) is an English engineer, designer and businessman.
Herd graduated from St Peter's College, Oxford with a double first in physics and engineering, before joining the Royal Aircraft Establishment in 1961 as a design engineer on the Concorde supersonic aircraft project. He worked on the Concorde project for four years and was eventually promoted to Senior Scientific Officer at the unprecedentedly young age of 24.
He was recruited by McLaren in 1965 and worked on cars, such as the Mallite-bodied M2A test car for the Firestone tire company. The M2A subsequently evolved into the Formula One M2B car. Herd stayed with McLaren until 1968 — during which time he designed their M4B, M5A and M7 Formula One cars — before moving to Cosworth to design a four-wheel drive F1 car. He co-founded March Engineering with Max Mosley, Alan Rees and Graham Coaker in 1969. The team completed 207 Formula One Grand Prix races between 1970 and 1992, winning three with four pole positions.
He sold March Racing to the Japanese property company Leyton House in 1989 and created Robin Herd Ltd., a design office in Bicester. He quit racing in 1995 and bought Oxford United Football Club, becoming Chairman, and also established a company investigating natural ways of producing energy. He resigned from his duty as Chairman in 1998, and formed an Indy Racing League team called March Indy International in the following year.
