Samuele Longo (born 12 January 1992) is an Italian professional footballer who plays as a striker for Spanish Primera Federación – Group 2 club Antequera.

Longo spent the rest of 2008–09 season in Treviso's Allievi Nazionali under-17 team[2][3] in a temporary deal before formally became an Inter player on 1 July 2009.

Longo was a junior member of Inter's reserve team in the 2009–10 season, as a backup for Denis Alibec, Mattia Destro and Simone Dell'Agnello.

In the 2010–2011 season, despite Inter trimming their reserve squad (only composed only of U18 and U19 players plus 3 U20), Longo was unable to become a regular starter, with 11 appearances, (2 starts) and 2 goals.

He also appeared in the league's play-offs, losing to eventual champions Roma in the semifinals, forming a partnership with Richmond Boakye; his side was also eliminated by Inter in the quarter-finals of 2011 Torneo di Viareggio.

Under Andrea Stramaccioni, Longo scored 5 goals in 2011–12 NextGen series as one of the team that won the tournament; his role also sightly changed after the arrival of Marko Livaja as new centre forward, in 4–2–3–1 (and later 4–3–3/4–3–2–1 formation under Daniele Bernazzani).

[14][15] Longo made his international debut on 9 August, coming on as a second half substitute in a 0–2 home loss against Hajduk Split for the season's Europa League.

[16] On 28 August 2012, Longo joined Spanish side RCD Espanyol of La Liga on a season-long loan deal,[17] following in the footsteps of Internazionale teammate Philippe Coutinho, who spent the final six months of the 2011–12 campaign at Estadi Cornellà-El Prat.

On 20 August 2013 Longo joined Verona, recently promoted to Serie A, in a season-long loan deal.

[26] On 5 July 2018, Longo was loaned to SD Huesca, newly promoted to La Liga, on a one-year deal with an obligation to make it permanent.

[34] On 29 January 2025, Longo returned to Spain and signed with Antequera in the third tier until the end of the season, with an option to extend.

[35] Samuele Longo made his U20 debut on 31 August 2011 as starting forward, the first match of coach Luigi Di Biagio.
