Leightoniella is a fungal genus in the family Pannariaceae. This is a monotypic genus, containing the single species Leightoniella zeylanensis, a cyanolichen.

The generic name honours English clergyman and botanist William Allport Leighton, who originally described the type species in 1870 as Pterygium zeylanense.
