Conus algoensis, common name the algoa cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.

Like all species within the genus Conus, these snails are predatory and venomous. They are capable of stinging humans, therefore live ones should be handled carefully or not at all.

There are four subspecies :

• Conus algoensis algoensis Sowerby, G.B. I, 1834 (synonym: Conus algoensis agulhasi Coomans, Moolenbeek & Wils, 1980)
• Conus algoensis norpothi Lorenz, 2015 (alternate representation: Conus (Sciteconus) algoensis norpothi Lorenz, 2015)
• Conus algoensis scitulus Reeve, 1849 (synonym: Conus scitulus Reeve, 1849)
• Conus algoensis simplex Sowerby, G.B. II, 1857 (synonym: Conus simplex G. B. Sowerby II, 1858 )
