Londonderry is a suburb of Sydney, in the state
of New South Wales, Australia. Londonderry is
60 kilometres west of the Sydney central
business district, in the local government area
of the City of Penrith and is part of the Greater
Western Sydney region.

Londonderry is located in the northernmost
part of the City of Penrith with the Driftway
forming the boundary with the Hawkesbury City
Council area. The Northern Road divides
Londonderry from Berkshire Park while
Cranebrook and Agnes Banks are its
boundaries on its southern and western sides.
Londonderry is a rural area and much of it still
crown land. Because of its closeness to
Richmond and distance from Penrith, the
suburb has always had stronger links with
Richmond than with Penrith.

Londonderry village in the centre of the suburb
is a vital community connection point for local
residents in the area. Amenities include shops,
service stations, a post office, a community hall,
Londonderry Public School and the
Londonderry Rural Fire Brigade station.
