Meaning & origin

Dejah is a rare American invention brought to life by Edgar Rice Burroughs's Barsoom novels. First recorded on the U.S. charts in 1973, the name reached its peak rank of 7,885 in 2025, a trajectory that has been falling since 1999. At its peak, it was given to roughly 1 in every 123,636 girls, reflecting its status as a distinctive, uncommon choice. While not a top pick in any state, Dejah carries a sci-fi glamour unique among literary coinages.

Dejah Thoris is the full name of the Martian princess in Edgar Rice Burroughs's Barsoom series, beginning with 'A Princess of Mars' (1912). The etymology of 'Dejah' is not rooted in any real language; Burroughs invented it to evoke an otherworldly elegance. The name has entered occasional use in the United States since the 1970s.
