"Lady Grinning Soul" is a ballad written by David Bowie, which is the final track on the album Aladdin Sane, released in 1973. The composer's first meeting with American soul singer Claudia Lennear in 1972 is often cited as the inspiration for the song.

The style of the piece has been compared to a James Bond theme.Pianist Mike Garson described his own performance as "about as romantic as it gets … French with a little Franz Liszt thrown in there".Rolling Stone's contemporary review called Bowie's singing "the album's most expansive and sincere vocal", while author Nicholas Pegg considers the track "one of Bowie's most underrated recordings … quite unlike anything else he has ever done". The song contains the highest note Bowie has sung on a studio album (G#5).

The track was used in the films The Runaways (2010) and Diana Vreeland: The Eye Has to Travel (2012).

According to artist Tanja Stark, Bowie was deeply influenced by psychoanalyst Carl Jung who described his famous archetypal concept of the Anima as a renaming of what the poet Carl Spitteler had called ‘My Lady Soul’ (Jung, 1968:13).
