The Riley Cars Archive Heritage Trust (RCAHT) is a charity registered with the UK Charity Commissioner (number 266905) dedicated to preserving and displaying historic documents and artefacts relating to the various Riley car manufacturing companies between 1898 and 1969.

In particular the Trust seeks to make more widely known the inspirational inventiveness and creativity of this Coventry family firm of engineers, their commercial and competitive successes and their influence on the development of British automotive engineering.

Its HQ is at the heritage quarter centred around Coventry's canal basin, a short walk from the city's Transport Museum, and is open at specific times (see website) and by appointment.

Much material is available online via the Trust's website,  along with archive material on site that can be visited for research purposes.
