Aloisius

Aloisius is a masculine name of Germanic origin, representing a formal Latin variant of Alois, which itself derives from Old German 'Alwis' meaning 'wise' or 'all-knowing.' The name gained prominence through several Catholic saints, most notably Saint Aloysius Gonzaga, a 16th-century Italian Jesuit. Aloisius maintains a traditional, scholarly character with classical Latin styling. While never among the most common names, it has maintained continuous usage particularly in Catholic European communities in Germany, Austria, and Italy. The name carries associations with intelligence, piety, and classical education. In contemporary usage, Aloisius might be perceived as formal or old-fashioned, though it offers potential for friendly nicknames like Al or Louis.

Pronounced al-oh-ISH-us.

As of October 2026, Aloisius ranked #4176 in US births in 1919 SSA.
