HMS Odin was a steam-powered first-class paddle frigate of the Royal Navy. She was launched in 1846 and was used in the Baltic theatre of the Crimean War. The ship was launched on 24 July 1846, at 1,301 73/94 bm, and decommissioned in 1865. She was sold that year to Castle & Beech for breaking up. She was initially intended to carry eight 32pdr carronades on the middle deck, but this idea was later discarded and these guns were never fitted. Between 1850 and 1851 she was outfitted for an Ambassador.
