The A41 is a trunk road between London and Birkenhead, England. Now in parts replaced by motorways, it passes through or near Watford, Kings Langley, Hemel Hempstead, Aylesbury, Bicester, Solihull, Birmingham, West Bromwich, Wolverhampton, Newport, Whitchurch, Chester and Ellesmere Port.

With the opening of the M40 extension in 1990 from junction 8, much of the route was downgraded. The sections between Bicester and the M42 near Solihull in the Midlands have been re-classified B4100, A4177 and A4141.
