Peacock & Son was a tanning and wool-brokering business in the early days of South Australia. Three members of the family were notable public figures: William Peacock (c. 1790 – 20 January 1874) was a successful businessman and one of the colony's first parliamentarians. His eldest son Joseph Peacock carried on the family business and was a member of parliament. His youngest son Caleb Peacock was a member of parliament and Mayor of Adelaide from 1875 to 1877, the first such born in the Colony.
