Meaning & origin

Sergei is the Russian form of the ancient Roman name Sergius, with roots possibly in Latin 'servus' meaning 'servant' or an older Etruscan name. It has been used in Russia since the adoption of Christianity and is strongly associated with Saint Sergius of Radonezh, a 14th-century monk who founded the Trinity Lavra. In the United States, the name first appeared in records in 1925 and reached its peak popularity in 1998y. As of 2025, it ranks 12,008th with an estimated 1 in 341,615 boys receiving the name, indicating stable but low usage. Sergei is rarely given in most U.S. states, reflecting its continued niche status as a culturally specific name.

Sergei is the Russian form of the Latin name Sergius, which is of uncertain origin. It may derive from the Latin word 'servus' meaning 'servant', or from an Etruscan root. The name was borne by several early Christian saints, including Saint Sergius of Radonezh, a highly venerated Russian monk. It has been a widespread name in Russia and other Slavic countries for centuries.
