"Inheritance" is the 162nd episode of the American science fiction television series Star Trek: The Next Generation, the tenth episode of the seventh season.

Set in the 24th century, the series follows the adventures of the crew of the Federation starship Enterprise-D. In this episode, as the Enterprise helps a planet to survive, Lieutenant Commander Data (Brent Spiner) must work with two local scientists, one of whom is revealed to be his mother.

The Enterprise arrives at Altrea IV, a planet with a core that is cooling and solidifying. Pran and Juliana Tainer, scientists from Altrea IV, inform the crew about the problem. Lieutenant Commanders Geordi La Forge (LeVar Burton) and Data suggest injecting plasma.

Juliana claims to be the former wife of Data's creator, Noonien Soong.

Data can only find one Juliana in his memory, a Juliana O'Donnell. She explains that after protests from her mother, she and Noonien decided to elope. A Klingon and a Carvalan Freighter captain served as marriage witnesses. She explains that his early memories were wiped and replaced with memories of the colonists of Omicron Theta. He was about to be reactivated when the Crystalline Entity attacked.

As they begin the plasma infusion, Juliana tells Data and La Forge a story about Data's trouble with learning to keep his clothes on. Data takes her to his quarters, where he plays his violin. She offers to play with him and uses a viola. Among his paintings, she sees one of his daughter, Lal. Juliana is upset. She was against Data being created due to the problems with Lore.
