The eleventh season of the Argentine version of the television reality show Gran Hermano was announced on 26 March 2023, by Telefe.

[3] The show follows a group of contestants (known as HouseGuests), who live in a house together while being constantly filmed and having no communication with the outside world as they compete to win a grand prize.

Each week, the HouseGuests compete in a Head of Household (HoH) competition which gives them immunity from nominations and the power to save one of the nominees up for eviction.

Bautista Mascia was crowned the winner of the season, with Emmanuel Vich finishing as runner-up and Nicolás Grosman in third place.

[7] The show follows a group of contestants, known as HouseGuests, who live inside a custom-built house outfitted with cameras and microphones recording their every move 24 hours a day.

[17] Former evicted HouseGuests Catalina Gorostidi, Isabel Denegri and Joel Ojeda returned to the house on Day 77 (25 February 2024).

[19] On Day 121 (9 April 2024), it was announced that former season 10 HouseGuest Constanza Romero would enter the house as a replacement via the Golden Ticket.

Color key: Gran Hermano is co-produced by production companies Kuarzo Entertainment Argentina and Banijay.

Casting for the season started on the same day of the announcement with open-call auditions held for people from up 18 years old.

[89] The winner of the series, determined by the audience, will receive AR$ 50 million pesos (invested by Mercado Pago) and a house.

The debates are joined by panelists Julieta Poggio, Sol Pérez, Gastón Trezeguet, Laura Ubfal, Ceferino Reato, Eliana Guercio, Marisa Brel, Costa and Pilar Smith.

Telefe airs in simulcast the season via YouTube and Twitch, hosted by Diego Poggi, Juan Ignacio Castañares, Lucila Villar and Daniela Celis, and the galas will become available to watch on the day after their premiere on Paramount's video streaming service Pluto TV.
