Lina Abarbanell (January 3, 1879 – January 6, 1963) was an American soprano who performed in grand and light opera and musical comedy. She made her debut at fourteen as Adele in the operetta DIE FLEDERMAUS, at the Royal Opera House in Berlin. She was first introduced to American theatergoers in 1905 as the soubrette in the Josef Strauss operetta Frühlingsluft (Spring Air). Abarbanell made opera history later that year as Hänsel in The Met's debut production of Engelbert Humperdinck's Hänsel und Gretel. Abarbanell spent the following near thirty years performing on Broadway and at venues across America. After her husband's death in 1934, Abarbanell left the stage, but remained active over virtually the remainder of her life as a Broadway casting director, producer, and stage director.
