The name Alaska is a girl's name of Native American origin meaning "great land". Alaska and is often added to lists like American Baby Names and discussed in our forums with posts like "Names on NB that make you go WOW!".
From the experts:
State name Alaska stems from an Aleutian word for the land mass itself. There were 39 girls named Alaska in 2012 and, in the drive to annex more place names as personal names, it's got potential. Wilder but as habitable as Dakota or Cheyenne, Alaska is a girls' name choice for the future.
