HMS Algiers was a 91-gun second rate ship of the line of the Royal Navy.

She was initially ordered from Pembroke Dockyard on 3 October 1833 as a 110-gun first rate to a design by Sir William Symonds.

The order was amended once more, to complete her as a 90-gun Albion-class ship of the line on 26 December 1840, and she was laid down at Plymouth Dockyard on 10 July 1843.

Afterwards, she saw service in Malta and was later a depot ship for the gunboat flotilla at Portsmouth.
