Dr George Bollen (12 April 1826 – 22 September 1892) was a homeopathic doctor in the colony of South Australia, a prominent citizen of Mount Barker and Port Adelaide, philanthropist and teetotaller.
Bollen was born in Brighton, Sussex, and emigrated to South Australia in 1854, arriving aboard the ship Albermarle in November, and in 1855 settled at Mount Barker, working as a cooper.
He returned to South Australia by the SS Alexandra in June 1873, settling at Port Adelaide, and opened a clinic on St Vincent Street, which developed a considerable patronage.
Bollen was well known as a preacher in the Wesleyan Methodist tradition, not only on the Port Adelaide circuit, but also at the Dunn Memorial Church in Mount Barker, where he had a summer residence.
Another instance of Bollen's philanthropy was his role, with E. Hounslow, in the 1879 formation of the Port Adelaide Seamen's Mission, of which he was elected president, a position he held until his death.
