Meaning & origin

Sigismund is a rare name of Germanic origin, first recorded in the United States in 1915. It reached a modest peak in the 1920s, with the highest usage in 1920, but has seen little use since. In the Social Security data for 2025, it appears with no rank and an estimated 1-in-n incidence too small to report. The name has never charted in the top 1000 and is neither rising nor falling in a statistically meaningful way; its trajectory is essentially flat. While famously borne by European royalty, Sigismund remains an obscure choice in the United States, favored by parents drawn to historical, strong-sounding names with a medieval feel.

Sigismund is a Germanic compound name derived from the elements 'sigu' (victory) and 'mund' (protection). It was borne by several medieval European monarchs, including Sigismund, Holy Roman Emperor in the 15th century, and Sigismund II Augustus, King of Poland. The name saw limited use in English-speaking countries, with a minor peak in the early 20th century in the United States.
