Algester is an outer suburb of City of Brisbane, Queensland, Australia. It is 18 kilometres (11 mi) south-west of the central business district. The suburb's population was estimated in the 2011 census at 8,262. The suburbs of Algester, Calamvale and now Parkinson, sit on the southern border or boundary of the City of Brisbane local government area with suburbs of Logan City such as Browns Plains and Regents Park.
The suburb's name is a corruption of the name of the English town of "Alcester". Briefly in the mid-to-late-1970s the suburb was colloquially named Ridgewood Heights after the Ridgewood Heights property development that then made up most of its land area, but had officially been known as Algester from 1972.
In the 2011 census, Algester recorded a population of 8,262 people, 51.3% female and 48.7% male.
The median age of the Algester population was 34 years, 3 years below the national median of 37.
58.5% of people living in Algester were born in Australia, compared to the national average of 69.8%; the next most common countries of birth were New Zealand 7.1%, England 4%, China 2.9%, Philippines 1.8%, India 1.5%.
70.9% of people spoke only English at home; the next most popular languages were 4% Mandarin, 2.2% Cantonese, 1.2% Spanish, 0.9% Hindi, 0.8% Vietnamese.
It was detached from Acacia Ridge and named in 1972, after the main road in the district. The road's name dates from about 1910 when a local family formed it and gave it the name 'Alcester', after an English town.
In 1968, Leighton Properties planned a suburban estate with the proposed name of 'Ridgewood Heights'. Whilst the estate's main access route retains that name, the Queensland Place Names Board, substituted 'Algester' in 1972. During this time, Algester Road and Dalmeny Street were connected as non-sealed roads and the only thoroughfare into the suburb, which was then still virgin bushland. Dalmeny Street ended at the first house to be built in the suburb known then as Lot 22 (now numbered as 133). These early residents were exposed to the abundance of native Australian flora and fauna, before development in the mid-1970s. Algester was heavily developed from the mid-1970s and has also seen considerable recent development. It forms part of the Brisbane Agricultural Reserve, which once covered a large area of southern Brisbane.
Algester Primary School  was founded in 1977 with a student population of about 200.
In July 2007, a major leak of an oil pipeline resulted in the forced evacuation of residents in Algester.
