Closed van and open pick up versions of the Morris Minor were built from 1953 until the end of production. They were designed for commercial use with small businesses, although many were also used by larger corporations. Van versions were popular with the General Post Office, the early versions of these (to around 1956) having rubber front wings to cope with the sometimes unforgiving busy situations in which they were expected to work. Both the van and the pickup differed from the monocoque construction of the Saloon and Traveller variants by having a separate chassis. They also differed in details such as telescopic rear dampers, stiffer rear leaf springs and lower-ratio differentials to cope with heavier loads.

The commercial versions were initially marketed as the Morris Quarter Ton Van and Pick-up, with a Series III designation applied from 1956. The names Morris 6cwt Van and Pickup were used following the introduction of the 1098cc engine in 1962 and 8cwt versions were added in 1968 with more substantial rear leaf springs.

As BMC's policy was to provide both Austin and Morris with complete commercial vehicle ranges, Austin-badged variants of the Minor van and pick-up were sold following the end of Austin A35 production in 1968. These featured Austin badging and the corporate Austin 'crinkle-cut' radiator grille but were otherwise identical to the standard Minor commercials, and were sold as the Austin 6cwt and Austin 8cwt.

Production of the Traveller and commercial versions ceased in April 1971, the convertible and saloon going out of production in 1969 and 1970 respectively.
