Ramón Gil Samaniego (February 6, 1899 – October 30, 1968), known professionally as Ramon Novarro, was a Mexican actor. He began his career in American silent films in 1917 and eventually became a leading man and one of the top box-office attractions of the 1920s and early '30s. Novarro was promoted by MGM as a "Latin lover" and became known as a sex symbol after the death of Rudolph Valentino. He is recognized as the first Latin American actor to succeed in Hollywood.

Novarro was born Ramón Gil Samaniego on February 6, 1899, in Durango City, Durango, north-west Mexico, to Dr. Mariano N. Samaniego, and his wife, Leonor Pérez Gavilán. The family moved to Los Angeles to escape the Mexican Revolution in 1913. Novarro's direct ancestors came from the Castilian town of Burgos, whence two brothers emigrated to the New World in the seventeenth century.

Allan Ellenberger, Novarro's biographer, writes:

The Samaniegos were an influential and well-respected family in Mexico. Many Samaniegos had prominent positions in the affairs of state and were held in high esteem by the president. Ramon's grandfather, Mariano Samaniego, was a well-known physician in Juarez. Known as a charitable and outgoing man, he was once an interim governor for the State of Chihuahua and was the first city councilman of El Paso, Texas.... Ramon's father, Dr. Mariano N. Samaniego, was born in Juarez and attended high school in Las Cruces, New Mexico. After receiving his degree in dentistry at the University of Pennsylvania, he moved to Durango, Mexico, and began a flourishing dental practice. In 1891 he married Leonor Pérez-Gavilán, the beautiful daughter of a prosperous landowner. The Pérez-Gaviláns were a mixture of Spanish and Aztec blood, and according to local legend, they were descended from Guerrero, a prince of Montezuma.

The family estate was called the "Garden of Eden". Thirteen children were born there: Emilio; Guadalupe; Rosa; Ramón; Leonor; Mariano; Luz; Antonio; José; a stillborn child; Carmen; Ángel and Eduardo. At the time of the Mexican Revolution, the family moved from Durango to Mexico City and then returned to Durango. Three of Ramón's sisters, Guadalupe, Rosa, and Leonor, became nuns. He was a second cousin of the Mexican actresses Dolores del Río and Andrea Palma.

Novarro began his film career in 1917, playing bit parts, supplementing his income by working as a singing waiter, a taxi dancer and as a dancer in revues choreographed by Ernest Belcher (father of Marge Champion). His friends, actor and director Rex Ingram and his wife, actress Alice Terry, began to promote him as a rival to Rudolph Valentino, and Ingram suggested he change his name to "Novarro". From 1923, he began to play more prominent roles. His role in Scaramouche (1923) brought him his first major success.

Novarro achieved his greatest success in 1925, in Ben-Hur. His revealing costumes caused a sensation. He was elevated into the Hollywood elite. As did many stars, Novarro engaged Sylvia of Hollywood as a physical therapist (although in her tell-all book, Sylvia erroneously claimed that Novarro slept in a coffin). With Valentino's death in 1926, Novarro became the screen's leading Latin actor, though ranked lower than his MGM contemporary John Gilbert as a leading man. Novarro was popular as a swashbuckler in action roles, and considered one of the great romantic lead actors of his day. He appeared with Norma Shearer in The Student Prince in Old Heidelberg (1927) and with Joan Crawford in Across to Singapore (1928).

He made his first talking film, starring as a singing French soldier, in Devil-May-Care (1929). He starred with Dorothy Janis in The Pagan (1929), with Greta Garbo in Mata Hari (1931), with Myrna Loy in The Barbarian (1933) and opposite Lupe Vélez in Laughing Boy (1934).
