Sara Allen (born March 23, 1954) is an American songwriter best known for her work with the duo Hall & Oates.
Working as a flight attendant in the early 1970s, Allen was introduced to John Oates, who subsequently wrote the song "Las Vegas Turnaround (The Stewardess Song)" which featured on the duo's second album Abandoned Luncheonette about Allen, who had begun a long-term relationship with Daryl Hall, which lasted until 2001. Hall then wrote the song "Sara Smile", Hall & Oates' first American hit from the duo's fourth album Daryl Hall & John Oates, about Allen in 1975.[1]
