Alastrianne is English in Origin.

Alastrianne is a rare, modern feminine elaboration of the Gaelic name Alastríona/Alastrìona, the Gaelic counterpart to Alexandra. The base ultimately derives from Greek Alexandros (alexein, “to defend,” + anēr/andros, “man, person”), yielding the meaning “defender of humankind.” The -ianne ending reflects French-influenced formations seen in names like Marianne or Vivianne, giving the name a lyrical, romantic cadence while preserving its Gaelic core.

Usage of Alastrianne itself is very limited and chiefly contemporary, whereas Alastríona/Alastrìona appear in Irish and Scottish Gaelic contexts, especially in revival-era and literary naming. Variant spellings and close relatives include Alastriona (without diacritics), Alastríona, Alastrìona, and the cognates Alexandra, Alexandrine, and Alexandrina; related masculine forms are Alasdair and Alistair. Possible pet forms are Alis, Alsa, Ally, Annie, or Rianne. Across its variants, the name carries a long association with protection and courage through its Alexander lineage.
