Buses in Lowestoft in the English county of Suffolk provide public transport in and around the town. Buses were first introduced in the town by Lowestoft Corporation Tramways in 1927 and replaced original tram services by 1931.
The corporation became Waveney District Council in 1974 and bus services taken over by Eastern Counties in 1977. The bus garage is on Rotterdam Road is still standing.
After bus deregulation in 1986 a range of operators took over services. In 2013 bus services in the town were operated by First Eastern Counties, Anglian Bus and Coaches, Nightingales of Beccles, Belle Coaches and Ambassador Travel. Routes within the town generally operate along key corridors linking the town centre with areas around the edge of the town. Services generally operate regularly during the day, becoming significantly less frequent during the evening. Some services, such as an orbital route around the town, are part funded by public money.
Bus services tend to be focussed on the bus station in the town centre, although the redevelopment of Lowestoft railway station aims to make the station a key interchange for bus routes as well. Traffic congestion, especially difficulty crossing Lake Lothing which cuts the town in two, can cause delays to bus services. Bus routes also connect the town to Norwich, Great Yarmouth and Peterborough as well as to surrounding villages and market towns and tourist destinations such as Pleasurewood Hills.
