Sir Horatio Thomas Austin was a British Royal Navy officer and explorer.

HMS Chanticleer was a Cherokee-class 10-gun brig of the Royal Navy. Chanticleer was launched on 26 July 1808. She served in European waters in the Napoleonic Wars and was paid off and laid up at Sheerness in July 1816. She was chosen for an 1828 scientific voyage to the Pacific Ocean. Her poor condition on her return meant that the Admiralty replaced her for the second voyage in 1831 with another Cherokee-class brig, Beagle, which subsequently became famous because of the association with Charles Darwin. Chanticleer then spent 15 years as a customs watch ship at Burnham-on-Crouch and was broken up in 1871.
