Robert Calder Allen CB (8 August 1812 – 28 January 1903) was an English naval captain.
[2] In 1850-51, he was master of the Resolute in the Arctic, under Captain Austin, whom he followed from the Blenheim, and was in charge of the magnetic observations.
In 1854-55 he was master of the Hogue blockship in the Baltic, and rendered efficient service by his survey, often under fire, of the approaches to Bomarsund.
The subordinate position in which so much of his service was passed prevented his name from coming prominently before the public; but in the navy his reputation as a sound and skilful navigator and pilot stood very high, and was officially recognised in his nomination to C.B.
His first wife brought him a daughter and four sons, who all entered the public service, navy, army, or marines.
