The Leyland Royal Tiger was a rear-engined coach built by Leyland between 1982 and 1988. It was intended to counter the offerings of foreign competitors such as DAF and Scania, but was not particularly successful, with only between 160 and 170 built.

The majority (around 60%) were sold as complete integral vehicles, in which case they were named Leyland Royal Tiger Doyen. Earlier examples were built at Leyland's subsidiary Charles H. Roe in Leeds, later ones at Workington in Cumbria. The remainder of the underframes were given Plaxton Paramount or Van Hool bodywork.

The Royal Tiger was fitted with Leyland's TL11 engine or in some cases the Cummins L10.

1950s Royal Tiger

The Leyland Royal Tiger name had previously been used for an early mid-engined chassis built from 1950 by Leyland. It was given the designation PSU1.

The lighter-weight Leyland Tiger Cub chassis was introduced in 1952 (which later spawned the successful Leopard), and this rapidly overtook the Royal Tiger PSU1 in popularity with British operators

Royal Tiger Worldmaster

In 1955, the Royal Tiger was re-engineered as the Royal Tiger Worldmaster (or just Worldmaster) primarily for export, and although it remained available in Britain, there were few further orders from the home market, while it was a success overseas.
