Henry Lamshed (11 April 1836 – 13 June 1918) was a farmer and politician in colonial South Australia.
Lamshed was born near Plymouth, England, a descendant of an old Newton Abbott, Devonshire, family.
He emigrated to South Australia on the Lord Hungerford, arriving at Port Adelaide in November 1856, and for several years worked on a farm at McLaren Vale.
He established a carrying business at Strathalbyn.
He took up land near Maitland when that district was first opened for settlement around 1875, and ran a farm there, "Oakwood", until around 1916, when he retired.
He was a member of the Strathalbyn District Council from 1867 and in 1888 was one of the foundation members of the Yorke's Peninsula District Council.
He was elected to the seat of Yorke Peninsula in the South Australian House of Assembly and served from April 1890 to April 1893 as a colleague of Harry Bartlett.
He died after several months' illness and was buried in Maitland.
