Gianluca Prestianni Gross (জানলুকা প্রেস্তিয়ানি) is an Argentine professional footballer who plays as a winger for Primeira Liga club Benfica and the Argentina national team.

Prestianni made his professional debut for Vélez Sarsfield in the Copa Libertadores on 24 May 2022 in match against Estudiantes. On 11 October 2023, he was named by English newspaper The Guardian as one of the best players born in 2006 worldwide.

On 22 December 2023, Vélez announced that they had reached an agreement with Portuguese club Benfica for the sale of Prestianni, with the deal commanding a fee of €9 million, plus €2 million in add-ons, and 85% of the player's economic rights. However, the deal was set to be completed only after the player's eighteenth birthday, on 31 January 2024. On that date, Benfica officially announced the transfer, with Prestianni signing a contract until 2029. His release clause was reportedly set at €100 million.

Prestianni has played internationally for Argentina at under-17 level. In March 2023, multiple media started reporting about Roberto Mancini's interest to call Prestianni to join the senior Italy national football team, just weeks after a similar move was successfully done for fellow Italian-Argentine Mateo Retegui.

In November 2025, Prestianni received his first call-up for the Argentina senior team, for a friendly against Angola.
