Most of Rosslyn Park started life as paddocks belonging to Dr Christopher Rawson Penfold, of Penfolds Wine. Dr Penfold was an English emigrant who purchased 500 acres (200 ha) of land in the area in 1844. Here he planted vines and established Penfolds as one of the leading winemakers in Australia. He and subsequent generations of his family resided at the Grange Cottage, to the east of Penfold Road.

Dr Penfold became the first chairman of the District Council of Burnside in 1856.

Upon Dr Penfold's death in 1870, his son-in-law, Thomas Hyland, assumed control of the business, and began to sell some of the land.

The area of Rosslyn Park to the west of Gordon Terrace, between Kensington Road and The Parade, was sold in 1877 to a syndicate made up of:

The syndicate subdivided the land, and sold parcels of it the next year.

Wine production declined at the Rosslyn Park site in the 20th century as production shifted to other areas in South Australia. The last vintage of Penfolds Wine was crushed at Magill Estate in 1972. Prior to and following this, subdivision of the land surrounding Magill Estate continued.

The area bounded by Penfold Road, Park Avenue, Edgcumbe Terrace and The Parade was formerly the site of Joseph Gillard Jnr's (manager at the Grange vineyard) main vineyard. It was sold and subdivided by the Penfolds in around 1912.

The area around Angove Court and Edgcumbe Terrace contains the former family home of Dr Roger Angove, inaugural President of the Burnside Historical Society. This land was subdivided in 1960. The family stables remained until they were demolished by a landowner in 1970.

A larger subdivision occurred in the early 1980s, when owners Tooth & Co sold much of the area to the east of Penfold Road, resulting in the survival of only the core of the former winery, including production plants and Grange Cottage.

In May 2002, Rosslyn Park experienced an incidence of freak weather when a tornado passed through it and Wattle Park late in the morning. The tornado cut a narrow, 2 km long path of destruction through the suburbs, tearing limbs off trees and tiles from roofs.

Rosslyn Park is situated approximately 6 km east of the Adelaide city centre. It is bounded by The Parade to the north, Coach Road to the east, Kensington Road to the south and Hyland Terrace to the west.
