Go South Coast is a bus operator in the south of England, owned by the Go-Ahead Group. It was established in late 2005, after Go-Ahead purchased Southern Vectis and its subsidiary Solent Blue Line, and combined its operations with existing subsidiary Wilts & Dorset. It is based in Poole, at the head office of Wilts & Dorset. Since it was created, the company has expanded with the acquisition by Solent Blue Line of Marchwood Motorways in October 2006.
