Anastacia is the Spanish and Portuguese spelling of Anastasia, from the Greek anastasis, "resurrection", a name early Christians gave to girls born around Easter. The American singer Anastacia, whose hits topped the charts in the early 2000s, made this spelling visible in the United States. Anastacia stood at number 1730 in 2000, peaked at number 1171 in 2003 and has stayed in the 2000s since, ranking number 2902 in 2025 with 58 births.
