Vicario is expected to challenge Spurs' captain Hugo Lloris, who is entering the final 12 months of his contract at the club, to be Ange Postecoglou's number one.
"We are delighted to announce the signing of Guglielmo Vicario from Empoli, subject to international clearance and a work permit," they wrote on their website.
The 26-year-old has impressed in the past two seasons at Empoli after spells at Udinese, Cagliari, Perugia and Venezia.
Vicario becomes Tottenham's second signing of the transfer window after Dejan Kulusevski's loan deal was made into a permanent move from Juventus.
