Stephen or Steven is a common English first name. It is particularly significant to Christians, as it belonged to Saint Stephen, an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr of the Christian Church.

Stephanie is a female name that comes from the Greek name Στέφανος (Stephanos) meaning "crown, wreath, garland". The male form is Stephen. Forms of Stephanie in other languages include the German "Stefanie", the Italian, Czech, Polish, and Russian "Stefania", the Portuguese Estefânia, and the Spanish Estefanía. The form Stéphanie is from the French language, but Stephanie is now widely used both in English- and Spanish-speaking cultures.
