Leonardo Fea (1852 - 1903) was an Italian explorer, zoologist, painter and naturalist.

Fea was born in Turin, and became an assistant at the Natural History Museum in Genoa. He made several foreign trips to collect specimens, including visits to Burma (1885) and the Cape Verde Islands (1898). He spent four years in Burma, accumulating large collections of insects and birds. He then planned an expedition to Malaysia, but his poor health made it necessary to choose somewhere with a drier climate, hence his visit to the Cape Verdes. He was disappointed by the amount of wildlife he found there, but was still able to collect forty-seven species of birds, eleven of which were new for the islands.

Whilst on the Cape Verde Islands Fea collected a specimen of an unknown petrel. This was named Fea's Petrel in 1899 by his friend Tommaso Salvadori. Several Burmese species were also named for him, including Fea's Muntjac (Thomas & Doria 1889), Fea's Viper (Boulenger 1888), Fea's Tree Rat (Thomas 1891) and Fea's Thrush (Salvadori 1887).
