Birute is of Lithuanian origin, meaning 'white' or 'pure'. It's a unisex name but traditionally more commonly given to females. The name gained popularity outside Lithuania after it was used by the protagonist in a novel written by Lithuanian-American author Sigitas Parulskis.
Birute experienced a slight increase in popularity between 1952 and 1953, with 12 births recorded in the latter year compared to 11 in the former. Overall, there were 23 babies named Birute during these two years combined.
