From Latin Stella Maris, meaning star of the sea, a poetic Marian title later used as a given name.
Stellamaris — or Stella Maris, the Sea Star — is one of the oldest and most evocative epithets in the Latin Christian tradition, applied to the Virgin Mary as early as the ninth century. The title derives from a reinterpretation of the Hebrew name Miriam: Jerome's Onomasticon glossed it as "drop of the sea" (stilla maris), which medieval scribes eventually transformed into "star of the sea" (stella maris) — a beautiful mistranslation that proved more poetically resonant than the original. Sailors across the Mediterranean and Atlantic seaboards prayed to Stella Maris before voyages, and the hymn "Ave Maris Stella" (Hail, Star of the Sea) became one of the most beloved of the medieval church.
As a given name, Stellamaris arrived in the Catholic tradition as an act of Marian devotion, particularly common in coastal communities of Italy, Spain, Portugal, and their colonial descendants in Latin America and the Philippines. The name carries within it the dual imagery of stars and ocean — two of humanity's oldest navigational guides — which gives it an almost mythological density. Lighthouses and maritime churches dedicated to Stella Maris dot the coastlines of the Catholic world from Barcelona to Haifa.
In contemporary usage, Stellamaris has attracted parents drawn to compound Latinate names — following the renewed enthusiasm for names like Seraphina, Celestine, and Rosalind. Run together as one word, it achieves something romantic and singular that the two-word form doesn't quite capture: a name that feels at once ancient and invented, devotional and poetic, specific enough to be meaningful and rare enough to feel like a discovery.
