Billie Nipper (November 22, 1929 – February 24, 2016) was an American artist who specialized in painting portraits of horses.

[2] She soon began to get commissions to paint Tennessee Walking Horses, particularly those involved in the upper levels of show competition.

She personalized her paintings by taking pictures of the actual horses to use for reference and in order to show correct proportions and individual characteristics.

Nipper's first World Grand Champion portrait was of that year's winner Shades of Carbon, and his trainer Judy Martin.

[4] For a time, Nipper operated in conjunction with the Tennessee Walking Horse Breeders' and Exhibitors' Association, but then went out on her own, saying, "Us artists like our independence".

[2] Nipper had a temporary office at the Tennessee Walking Horse National Celebration each year, from which she displayed and sold her work.

[5] In many of her World Grand Championship portraits, Nipper painted a montage depicting the horse's life and show career.

[2] In the mid-1970s, Nipper began to have her oil paintings made into prints, after getting requests from people who could not afford the originals.

[2] Nipper's work was also transferred onto Gorham china, decorative objects such as music boxes, and made into wallpaper borders.

[2] The city of Cleveland, Tennessee has held an annual art show in honor of Nipper each fall for over 40 years.

[7] However, the first year the festival was held, many people called the local newspaper office to complain that the organizers had gotten Nipper's name wrong.
