Frederick Thomas Crowder (January 1850 – 1902), generally referred to as F. T. Crowder, was an Australian businessman and politician and member of the Western Australian Legislative Council for two terms: in 1894–1900 representing South-East Province, and 1901–1902 representing East Province. He died in office and was succeeded by William Loton.

Crowder was born in Franklin Street, Adelaide, the second son^[1] of William Nathaniel Crowder (c. 1818 – 2 February 1898) who arrived in South Australia in 1839 on the barque Singapore. His wife Emily (c. 1829 – December 1867) is not recorded as a passenger, and it is likely they married around 1850.^{[lower-alpha 1]} W. N. Crowder ran J. H. Fisher's dairy at The Reedbeds,^[2] until the early 1850s, spent some time unprofitably at the Victorian goldfields, then in 1854 took over the insolvent George Malcolm's aerated water and cordial manufacturing business in Franklin Street^[3] which he ran successfully then sold to Charles Downer and John Henderson in 1881.^[4] They had a home "Olive Villa" in Lower Mitcham, which still stands.^[5]

Crowder was educated at J. L. Young's Adelaide Educational Institution and after leaving school joined his father's business, married in 1876, then in 1878 left Adelaide for Western Australia with William Letchford^[6] to open an aerated water and cordial business of Crowder and Letchford in Essex Street, Fremantle^[7] in 1878.^[8] They won prizes at the 1881 Exhibition.^[9] and opened a factory in Goderich Street, Perth, in 1884, whose assets were sold to Crowder and Letchford Ltd. in 1896,^[10] later purchased by the firm of Donaldson and Collins.

In 1894 he was appointed director of Mount Eva Mining company with a goldfield at Coolgardie.^[11]

His wife died and sometime later he remarried and retired from manufacturing business.

He was for twenty years chairman of directors of Perth Gas Company.^[12]

He served for some time on the Perth City Council then in 1894 entered Parliament as member for the South-East Province of Perth, and was subsequently nominated as a delegate to the Federal Convention, and had the opportunity to revisit Adelaide and meet his old schoolmates. He opposed the entrance of Western Australia into the Federation so resigned his seat, but a year later he was elected to the West Australian Legislative Council for the Central division. He was returned unopposed for the East province a fortnight before his death at his home "Abbeyfeale View" at Cottesloe Beach.^[13]
