Page "Etruscan language" Paragraph 13

The majority consensus is that Etruscan is related only to other members of what is called the Tyrsenian language family which is an isolate family, that is, unrelated to other language groups by any known relationship ( see Language isolate ).

Since Rix ( 1998 ), it is widely accepted that Tyrsenian is composed of Rhaetic and Lemnian together with Etruscan.
