Busways is an Australian bus company operating services in Sydney, and in the Central Coast, Mid North Coast regions of New South Wales and Adelaide. It is the largest privately owned bus operator in Australia.

The origins of Busways can be traced to 1942 when Dick Rowe commenced a hire car service from Rooty Hill to Plumpton. In 1946 Rowe purchased his first bus and further expansion saw a depot established in Plumpton in 1958.

In 1958, in partnership with Fred Bowman, Rowe purchased Parramatta-Villawood Bus Service followed by Campbelltown Transit on 13 May 1967 in partnership with Roger Graham and Jim Newport. In 1970, Rowe had taken full ownership of Campbelltown Transit and in January 1978 sold out of Parramatta-Villawood.

In 1984, Riverstone Bus Service was purchased and merged with Rowe's Bus Service. In June 1986 Higlett's Motor Coach Services, Camden was purchased and rebranded Macarthur Coaches.

In 1988, Campbelltown Transit, Macarthur Coaches and Rowe's Bus Service were all rebranded as Busways. In February 1990 the Seargent's, Charmhaven business on the Central Coast was purchased followed in July 1994 by the neighbouring Peninsula Bus Lines business in Kincumber, Ourimbah and Umina.

In June 1991, the Campbelltown to Wollongong service of Farmborough Coaches was acquired. In November 1992 Busways took over operation of the routes of Leslies, Arndell Park following its collapse before purchasing them in May 1993.

In September 2003, Busways purchased the Great Lakes and Mid North Coast services of King Brothers from its administrator. In January 2008 the school services of Yarramalong Bus Lines, Wyong were purchased followed by those of Kulnura Bus Lines in July 2009.

Between 2014 and 2015, Busways attempted to venture overseas by submitting a bid for the Bulim Bus Package in Singapore. It was among the 10 local and foreign bus operators who had submitted a bid for the tender. The bid was ultimately unsuccessful.
