The Fulke Walwyn Kim Muir Challenge Cup is a National Hunt steeplechase in Great Britain for amateur riders; it is open to horses aged five years or older.
It is a handicap race and it is scheduled to take place each year during the Cheltenham Festival in March.
The event was established in 1946 and it was originally called the Kim Muir Amateur Riders' Steeplechase.
It was introduced by Mrs Evan Williams and was named in memory of her brother, Kim Muir, a cavalry officer who lost his life during World War II.
Only professional jockeys competed in the 2021 running as amateur riders were excluded from the Cheltenham Festival due to restrictions on grassroots sport for the COVID-19 pandemic in the United Kingdom.
