Neptunit ist ein Silikatmineral, das durch die Formel KNa2Li(Fe2+, Mn2+)2Ti2Si8O24 gekennzeichnet ist. Es bildet eine Reihe mit Mangan-Neptunit, wenn der Mangangehalt zunimmt, während Watatsumiit eine Variante ist, bei der Vanadium Titan in der Zusammensetzung ersetzt. Neptunit wurde erstmals 1893 im Narssârssuk-Pegmatit in Westgrönland identifiziert und kommt auch in Natrolithadern innerhalb von Glaukophanschiefer im San Benito County, Kalifornien, sowie in Mont Saint-Hilaire, Quebec, und auf der Kola-Halbinsel in Russland vor. Das Mineral leitet seinen Namen von Neptun, dem römischen Meeresgott, ab, aufgrund seiner Verbindung mit Ägirin, benannt nach Ägir, der skandinavischen Meeresgottheit.
