Grenfell is a country town in Weddin Shire in the Central West of New South Wales, Australia. It is 370 kilometres west of Sydney and five hours' drive from the city. It is close to Forbes, Cowra and Young. At the 2011 census, Grenfell had a population of 1,996.
Prior to European settlement the Grenfell area was home to the Wiradjuri Aborigines. Grenfell is a goldmining town first known as Emu Creek and renamed in honour of John Grenfell, Gold Commissioner at Forbes, who had been killed in 1866 when bushrangers attacked a stagecoach on which he was travelling. Weddin Post Office opened on 3 December 1866 and was renamed Grenfell on 24 December the same year. By 1870-71 it was producing more gold than any other town in NSW. However by the mid-1870s gold was in decline. Wheat was first grown in the district in 1871. In late October 1901, the railway from Koorawatha to Grenfell was officially opened. Unlike most Australian country towns Grenfell has a main street which bends.
