Danilo d'Ambrosio (born 9 September 1988) is an Italian professional footballer who plays as a centre-back or right-back for Serie A club Monza.

[3][4] On 11 July 2008, D'Ambrosio joined Lega Pro Prima Divisione side Juve Stabia in another co-ownership deal, for €30,000,[5] making his debut for Le vespe on 31 August 2008 against Taranto.

[15] New head coach Giampiero Ventura decided to focus on D'Ambrosio for the 2011–12 season, playing him as right back with Matteo Darmian.

[citation needed] D'Ambrosio made his Serie A debut on 26 August 2012 during the goalless draw against Siena, appearing as a 93rd-minute-substitute, but did not start until 26 September against Udinese (0–0).

[26] On 28 January, Tuttosport revealed that the fee was €1.75 million cash plus the free loan of Matteo Colombi and 50% of the registration rights of Marco Benassi.

D'Ambrosio was an unused substitute in Javier Zanetti's last competitive match at the San Siro, in which Inter defeated Lazio 4–1 to secure a place in UEFA Europa League play-off for next season.

[citation needed] D'Ambrosio scored his first competitive goal for Inter on his European debut, a 3–0 away win over Stjarnan in the first leg of Europa League play-off.

[citation needed] On 20 February 2016, D'Ambrosio scored his first league goal for Inter during the 3–1 home win over Sampdoria, beating the goalkeeper with a volley in with the inside of his left boot at the back post.

[43] D'Ambrosio won more playing time under head coaches Frank de Boer and Stefano Pioli, starting all the match except in October, as he was the second outfield player with most balls recovered.

[49] In the final matchday of the season, his goal in the 29th minute versus Lazio served as a temporary equalizer in an eventual 3–2 win at Stadio Olimpico which meant the return of Inter in UEFA Champions League after six years.

[51] The following year, D'Ambrosio found less space due to physical problems[52][53] (albeit playing both as a left midfielder and as a central defender in coach Antonio Conte's three-man defence),[54] but, in addition to scoring a goal that decided the match against Lazio on 25 September 2019,[55] he reached 200 appearances for the nerazzuri on the occasion of the 4–0 win against SPAL on 16 July 2020.

[61] A starter in the path that took the team to the Europa League final,[62] on 17 August he scored the second goal in a 5–0 win against Shakhtar in the semi-finals.

[64] In the 2020–21 season, D'Ambrosio was relegated to a supporting role, despite scoring three goals, but he was able to celebrate winning his first Serie A championship with Inter, as well as his first professional trophy.

[66] On 12 January 2022, despite not playing, D'Ambrosio won his second trophy with Inter, the Supercoppa Italiana, beating Juventus 2–1 after extra time.

[75] At the end of the season, D'Ambrosio left Inter at the natural expiry of his contract, having played 284 games and scored 21 goals in all competitions.

[76][77] On 2 August 2023, D'Ambrosio signed a one-year contract with Serie A side Monza as a free agent, with an option for renewal.

[88] In April 2014, D'Ambrosio joined Twitter and with his first post claimed that for every follower he received, he would make a donation of €0.50 to the "Aiutare I Bambini" charity which gives aid to needy children in his home region of Campania.
