Alderisi is an Italian surname with a patronymic origin, meaning "son of Alderissius". The root name Alderissius is a Latinized form of a Germanic personal name whose etymological meaning is unknown. The Germanic element likely contained a prefix akin to adal (noble) or ald (old), but without direct attestation the precise original form remains obscure. The use of Latinization was common in medieval Italian records, where vernacular names were given a Latinate ending for official documents.
The surname is particularly concentrated in Italy, especially in regions historically influenced by Lombardic (Germanic) settlement, such as central and northern Italy. Like many Italian patronyms formed with the suffix -esi (often derived from Latin -ensis meaning "of" or "from"), Alderisi indicates "descendant of Alderissius." This pattern parallels other Italian surnames such as Adami or Bernardini.
Among notable bearers, Francesca Alderisi (born 1968) is an Italian politician and television presenter. Elected to the Senate of the Republic in 2018 representing the foreign constituency of North and Central America for Forza Italy, she has also hosted the worldwide Rai International program Sportello Italia. Her political and media work make her the most prominent living namesake.
