The Dennis Pax was a coach built by the Dennis Brothers. The bus was produced during the 1950s and 1960s. The updated version was built from 1964 to 1968 and only 13 were produced.

The Pax was based on the chassis Dennis Truck of the same name.

In 1959, Dennis fitted a chassis with a P6 diesel engine from Perkins. The nineteen long-nosed buses arrived at Kowloon Motor Buses, in the then British colony of Hong Kong, where they were used. Their withdrawal was made ​​in the second half of the 1960s.

In 1962, a single BVD6 chassis was fitted with a body from Sully, provided for Blackford & Hawkey with 30 seats. The production from 1958 of the COE Pax II resulted in 11 buses being made.

Only two copied of the Pax V were made. They were a 33-seat bus and delivered to Llandudno Urban District Council.
