Jeanette Loff (born Janette Clarinda Lov; October 9, 1906 – August 4, 1942) was an American actress, musician, and singer who came to prominence for her appearances in several Pathé Exchange and Universal Pictures films in the 1920s.

Born in Idaho, Loff was raised throughout the Pacific Northwest, and began singing professionally as a lyric soprano and performing as an organist while a teenager in Portland, Oregon.

After moving to Los Angeles, California, Loff was signed to a film contract by producer Cecil B. DeMille, with Pathé Exchange in 1927.

Her father, a farmer and a barber who played the violin in local orchestras,[6] was a first-generation American born to Danish parents.

[13] Loff's motion picture career began with an uncredited role in the 1927 silent film adaptation of Uncle Tom's Cabin.

Her absence from the film industry was noted in a 1933 issue of Motion Picture Magazine, in addition to speculation about her personal life: Jeanette Loff, who has been absent from Hollywood for some time, seems to have been able to make Gilbert Roland forget all the other girls he has been interested in since his break with Norma Talmadge, if you care to believe the idle tongues of the cinema city.

Miss Loff is planning to go on tour with Buddy Rogers and his band on the West Coast and later hopes to return to the screen.

[21]Around 1934, Loff relocated to New York City and appeared in musical plays and with orchestras, before returning to films with a role as a country girl in Flirtation.

[citation needed] On August 1, 1942, Loff ingested ammonia at the Beverly Hills home she shared with husband Friedlob on 9233 Doheny Road.
