Amaro is an Italian name of Latin origin, meaning 'dark' or 'bitter'. It has been traditionally used as both a given name and a surname. In Italy, Amaro is often associated with the region of Friuli-Venezia Giulia, where it is relatively common. The name's popularity can be attributed to its historic use among Italian nobility, with notable figures such as Amaro Pargo, a legendary Spanish-Basque privateer born in the 18th century, bearing this name.
The name Amaro experienced a significant surge in popularity starting from the year 2017 onwards. Prior to that, it maintained a relatively low and consistent number of births annually, fluctuating between 5 and 6 births per year over a span of almost four decades (1977-2016). However, since 2017, there has been a substantial increase in the number of newborns named Amaro, with 180 total births recorded between 1977 and 2023.
