Count Alfredo Caruana Gatto (3 September 1868 – 15 October 1926) was a Maltese lawyer, politician and naturalist.

[1] Caruana Gatto was an avid naturalist with a particular interest in botany and ornithology, and he was a member of the Società botanica italiana [it], the Société Botanique de Paris and the Linnean Society of London.

He contributed to The Mediterranean Naturalist between 1891 and 1893, wrote a paper for the 1892 International Botanical Congress in Genoa, and co-authored the 1915 book Flora melitensis nova with Stefano Sommier [it].

[2] On 1 April 1926, Caruana Gatto allegedly purchased two sheets of a newly-issued postage stamp with a unique printing error which were then sold to speculators for a profit.

[1] A minor controversy later arose about how the stamps had been acquired, but the findings of a 1930 investigation on the matter by a government-appointed committee were inconclusive.
