|Linguistic classification:||One of the world's primary language families|
|Glottolog:||nucl1708 (Nuclear Torricelli)|
The Torricelli languages are a language family of about fifty languages of the northern Papua New Guinea coast, spoken by only about 80,000 people. They are named after the Torricelli Mountains. The most populous and best known Torricelli languages are the Arapesh, with about 30,000 speakers.
The Torricelli languages occupy three geographically separated areas, evidently separated by migrations of Sepik-language speakers several centuries ago.
Wilhelm Schmidt linked the Wapei and Monumbo branches, and the coastal western and eastern extremes of the family, in 1905. The family was more fully established by David Laycock in 1965. Most recently, Ross broke up Laycock and Z’graggen's (1975) Kombio branch, placing the Kombio language in the Palei branch and leaving Wom as on its own, with the other languages (Eitiep, Torricelli (Lou), Yambes, Aruek) unclassified due to lack of data.

Ethnologue also lists Bragat in the Palei branch.
The Torricelli languages are unusual among Papuan languages in having a basic clause order of SVO (subject–verb–object). (In contrast, most Papuan languages have SOV order.) It was previously believed that the Torricelli word order was a result of contact with Austronesian languages, but it is now thought more likely that SVO order was present in the Torricelli proto-language. 
The pronouns Ross reconstructs for proto-Torricelli are,
I *ki we two *ku-p we *ku-m, *əpə thou *yi, *ti you two *ki-p you *ki-m, *ipa he *ətə-n, *ni they two (M) *ma-k they (M) *ətə-m, *ma, *apa- she *ətə-k, *ku they two (F) *kwa-k they (F) *ətə-l
