William McMinn (1844 – 14 February 1884) was an Irish-born Australian surveyor and architect, based in Adelaide in the colony of South Australia.

Following a breakdown of morale in the settlement, McMinn and six others (Stow, Hamilton, Hake, Edwards, White, and Davis, the last two being boatmen) purchased a 23-foot open boat which they dubbed the Forlorn Hope and sailed it 2,000 miles (3,200 km) to Champion Bay, near Geraldton, Western Australia.
