Marino is a suburb in the south of Adelaide, South Australia. It sits on coastal hills overlooking Gulf St Vincent, within the City of Marion local government area. It neighbours Seacliff, Hallett Cove and Kingston Park.
The suburb features the Marino Rocks beach which has a steep cliff face and then a low and flat rocky beach, leading out to a reef on the southern end of Seacliff. Fishing and snorkelling are common recreation activities.
At the northern end of the beach, the public artwork Contemplation can be viewed, by artist Marijana Tadic. Launched in 2006, the artwork takes the form of a rocked boat.
Also as of 2006, at the access point to the beach, there is mosaic artwork on the outer walls of the toilet facility. These were designed and constructed by South Australian artist Michael Tye. Michael worked with local artists and community members in the design and construction of the mosaic artwork along the nearby retaining wall.
The Seaford railway line passes through the suburb, and there are two railway stations: Marino and Marino Rocks. The line has had an active history, first being built In 1913 to Marino and extending to Willunga in 1915. The section from Hallett Cove to Willunga was closed in 1969. In the 1970s the line was extended south from Hallett Cove, reaching Christie Downs in 1976 and Noarlunga Centre in 1978.
A number of walking trails are available through Marino including the Coastal Walk and the Coast to Vines rail trail.
