Carl Julian (von) Graba (17 February 1799 in Itzehoe – 30 March 1874 in Kiel) was a German lawyer and Royal Danish judicial councillor, and was also a keen ornithologist and one of the first modern researchers to visit and study the Faroe Islands, where he described the local puffin which was subsequently named Fratercula arctica grabae after him. Graba's findings were mentioned in 1872 by Charles Darwin in his book On the Origin of Species.
