Meaning & origin

Sixto, from Latin 'Sextus' meaning sixth, has a long history rooted in Roman naming traditions and later Catholic veneration. In the United States, its earliest recorded use dates back to 1915. The name saw its peak popularity in 1994, and since 2018 it has been on a rising trajectory, with 2025 ranking at 6,803 and an incidence of roughly 1 in 142,340 births. Particularly favored in Texas, Sixto appears across Spanish-speaking communities. Its rarity and strong numerical meaning appeal to parents seeking a distinctive but traditionally grounded name.

Derived from Latin 'Sextus', meaning 'sixth'. Traditionally given to the sixth child, or a child born in the sixth month. The name was used in ancient Rome and later adopted in Spanish and Italian cultures, often in honor of Catholic saints such as Pope Sixtus I, II, and III.
