Marjorie Goetschius (23 September 1915 – 7 May 2001) was an American composer, pianist, cellist, and singer. Born in Raymond, New Hampshire, she was the granddaughter of opera singer Maria Stefany and music theorist Percy Goetschius. Marjorie learned piano from her mother, Pauline Gaiser, a concert pianist, starting at the age of five. She was educated at Georgian Court College and received further musical instruction at the Juilliard School in New York City, studying under Bernard Wagenaar, James Friskin, and Joseph Schillinger.

At Juilliard, she met her husband, Emery Deutsch, who encouraged her to compose popular songs. Her song "I Dream of You" was a hit, remaining on the charts for 16 weeks in 1944–45. Goetschius collaborated with violinist Jascha Heifetz, who used the pseudonym Jim Hoyl, and wrote "My Bambino" in 1954, inspired by the birth of her son.

Marjorie's compositions were performed by renowned artists such as Frank Sinatra, Ray Charles, Doris Day, Duke Ellington, and Johnny Mathis. Her classical works include pieces for piano and violin, such as "Sonata in B" and "Lament." She left a legacy of popular songs including "I'll Always Be With You" and "So Much in Love."
