Lecania hydrophobica is a species of crustose lichen in the family Ramalinaceae.

Found in Alaska, it was described as a new species in 2020 by Toby Spribille and Alan Fryday.

The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park.

Here it was found at an altitude of 9 m (30 ft) growing on a vertical shale outcrop.

Lecania hydrophobica is abundant on sheltered rock overhangs in the type locality, and is also known to occur further south – on southern Baranof Island, and in British Columbia.
