Ranella is a genus of large warm-water and tropical sea snails, marine gastropod molluscs in the family Ranellidae, the tritons.^[1]

The shells of species within this genus are very large and solid, with a tall spire, a rounded aperture, a broadly flanged outer lip, and a moderately long siphonal canal, which is flexed and inclined to the left. The varices are prominent and rounded, but are hollowed out on the inside.

Species within the genus Ranella include:

• Ranella australasia (Perry, 1811)
• † Ranella bellardii (Weinkauff, 1868)
• Ranella gemmifera (Euthyme, 1889)
• †Ranella kaiparaensis (Finlay, 1924)
• Ranella olearium Linnaeus, 1758
