Chiara is an Italian given name derived from the Late Latin word "clarus", meaning "clear", "bright", or "shining". The name has its roots in ancient Rome and the Latin language, which was spoken throughout the Roman Empire.

The name Chiara gained popularity during the Middle Ages in Italy, particularly after the life of St. Clare of Assisi (1194-1253), one of the first followers of St. Francis of Assisi. St. Clare founded the Order of Poor Ladies, also known as the Poor Clares, and her name became associated with purity, clarity, and devotion.

One of the earliest recorded uses of the name Chiara can be found in Dante Alighieri's Divine Comedy, written in the early 14th century. In the epic poem, Dante mentions a woman named Chiara, who is believed to be a reference to St. Clare of Assisi.

Throughout history, several notable women have borne the name Chiara. Chiara d'Assisi (1193-1253), better known as St. Clare of Assisi, was a close friend of St. Francis and the founder of the Poor Clares. Chiara Gambacorti (1370-1420) was an Italian noblewoman and the ruler of Pisa during the Renaissance period. Chiara Lubich (1920-2008) was an Italian Catholic activist and the founder of the Focolare Movement, a worldwide movement for spiritual renewal.

Other famous Chiaras include Chiara Frugoni (1940-), an Italian historian and academic; Chiara Mastroianni (1972-), a French actress and the daughter of actors Catherine Deneuve and Marcello Mastroianni; and Chiara Ferragni (1987-), an Italian fashion blogger and influencer.

The name Chiara has maintained its popularity in Italy and other parts of the world, particularly among those of Italian descent. Its meaning of clarity and brightness has made it a favored choice for parents seeking a name with a positive and uplifting connotation.
