Knowsley Hall is a stately home near Liverpool in the Metropolitan Borough of Knowsley, Merseyside, England. It is the ancestral home of the Stanley family, the Earls of Derby. The hall is surrounded by 2,500 acres of parkland, which contains the Knowsley Safari Park. Though the hall is still owned by the Stanley family, it is no longer a family home, but is instead used for corporate events, conferences and weddings. Since 1953, it has been designated a Grade II* listed building.
