Lanette is a feminine given name of French origin, derived from the Old French name Alenette, a diminutive form of the name Alaine or Alene. The name Alaine itself is believed to have evolved from the Germanic name Alana, which means "precious" or "little dear one."

The earliest recorded use of the name Lanette can be traced back to the 13th century in France, where it was a popular name among the nobility and upper classes. It was often bestowed upon daughters as a sign of affection and endearment.

One of the earliest known historical figures to bear the name Lanette was Lanette de Châtillon, a French noblewoman who lived in the late 12th and early 13th centuries. She was the daughter of Gaucher III de Châtillon, a prominent crusader and military leader during the Third Crusade.

In the 15th century, Lanette de Bourbon was a French princess and the daughter of Charles I, Duke of Bourbon. She was born in 1408 and married John II, Count of Penthièvre, in 1424.

During the Renaissance period, the name Lanette gained popularity among the artistic and literary circles of France. Lanette de Longwy, a French poet and writer, was born in 1543 and is known for her contributions to the French Renaissance literature.

In the 17th century, Lanette de Rochefort was a French noblewoman and the mistress of King Louis XIV of France. She was born in 1663 and played a significant role in the court of Versailles.

Another notable figure bearing the name Lanette was Lanette de La Vallière, a French duchess and mistress of King Louis XIV. She was born in 1644 and is remembered for her influential role in the French court during the reign of the Sun King.

While the name Lanette has its roots in France, it has since spread to other parts of the world, particularly in English-speaking countries, where it is considered a variation of the name Annette or a combination of the names Laney and Etta.
