Meaning and origin of Trinity
Trinity is an English and Latin name that means “threefold; the Holy Trinity”.
Trinity comes from the Latin trinitas, "a group of three" or "threefold", and in Christian theology it names the union of Father, Son and Holy Spirit. Many churches, colleges and places carry the name, including Trinity College in Cambridge and Trinity College Dublin. As a given name it became popular in the United States from the late twentieth century, part of a trend toward names with spiritual meaning that are not taken from biblical characters. Trinity has a light, rhythmic three-syllable sound. Trin and Trini are possible nicknames, and the name feels both devout and contemporary.
Popularity over time
Trinity first appears in US Social Security records in 1921. It has ranked in the top 1,000 in 39 different years, starting in 1974. Its best national rank was #48 in 2004, the same year it reached its highest count of 5,638 babies. In 2025, 725 babies were named Trinity, and it ranked #428 nationally. That is 71% fewer than ten years earlier, so it is becoming less common.
