- In Roman religion Lemuria is the Feast of the Lemures, during which the unwholesome and malevolent spectres of the restless dead (lemures) were propitiated.
- Lemuria is the name given by 19th century geologist Philip Sclater to a hypothetical land mass in the Indian Ocean that was required, before the understanding of plate tectonics, to account for similarities between fauna India and Madagascar. The name derived from the lemurs that are endemic to Madagascar, who received their name from their noctural habits and spectral night howling.
- Lemuria is also the name of an album released by the Swedish heavy metal band Therion in 2004.
