Alessandro Bastoni (born 13 April 1999) is an Italian professional footballer who plays as a defender for Serie A club Internazionale.
Bastoni was born in Casalmaggiore, Lombardy, and began his career in the local Cannatese youth side, where his father was coach. At the age of 7, he joined the youth sides of Serie A side Atalanta.
Bastoni progressed through various age groups at Bergamo, including making nearly 30 appearances for the under-17 side, before eventually progressing to the Primavera side, where he established himself as a regular starter at the centre of defence. He was named on the first-team bench for the first time on 30 October 2016, for the game against Genoa, and made his full debut a month later in the Coppa Italia game against Pescara, playing the full game in a 3–0 victory. In Serie A, Bastoni remained as an unused substitute for the six games after Genoa until making his debut in a 1–0 win over Sampdoria on 22 January 2017, playing full 90 minutes.
