Lionel Sebastián Scaloni (লিওনেল এস্কালোনি) is an Argentine professional football manager and former player who is the current head coach of the Argentina national team. Under his leadership, Argentina achieved the 2022 FIFA World Cup. Scaloni is regarded as one of the best men’s national coaches in the world. A versatile player, he operated as a right-back or right midfielder.

Born in Pujato, Santa Fe, Scaloni debuted as a player for Newell's Old Boys in 1995. He spent most of his professional career in Spain, mainly at Deportivo de La Coruña, where he won the 1999–2000 Spanish league title and the 2001–02 Copa del Rey. In total, he amassed 258 games and 15 goals over 12 seasons in La Liga with three different teams. He also played for several years in Italy, with Lazio and Atalanta, before retiring in 2015. Internationally, he played for Argentina at under-20 level, and made his debut for the senior team in 2003; he won seven caps for the team between 2003 and 2006, and was part of their 2006 World Cup squad.

After making his debut for Argentina on 30 April 2003 in a friendly game with Libya, Scaloni was a surprise selection for the 2006 FIFA World Cup, taking the place of veteran Javier Zanetti who also played as a right wing-back. His only appearance of the tournament was the 2–1 extra time win against Mexico in the round of 16, on 24 June 2006 at the Zentralstadion, which he started and finished.

Scaloni is regarded as one of the best men’s national coaches in the world due to his success with the Argentina national team. Scaloni has stated that Carlo Ancelotti is the coach he most admires and that he tries to emulate his coaching style with Argentina. In his time as coach of Argentina, the national press nicknamed the national team 'Scaloneta'.

Scaloni has instilled a coaching philosophy with Argentina centered on fostering unity and camaraderie among players through team bonding and ensuring clear, open communication to define each player’s role and value within the team structure.

Scaloni has both Argentine and Italian citizenship. His older brother, Mauro, also played at Deportivo, but never made it beyond its reserve team. He and his wife Elisa Montero have two sons. Furthermore, a street was named after him in his hometown of Pujato.

In April 2019, Scaloni was run over while cycling in Calvià in Majorca. Some media initially reported him to be in serious condition, but he was discharged a few hours later.
