Gran Hermano (Argentine TV series) season 10

The tenth season of the Argentine version of the television reality show Gran Hermano was announced on 21 June 2022 by Telefe. After last airing on América TV in 2016, the show made its return to the original network Telefe, and it would be the first series to air in the network since the seventh season that aired during 2011–2012.

Santiago del Moro was formally announced as the show's new host. 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 of over ARS15 million and a house. The runner-up also wins a house, and a vacation trip for two was given to the third place contestant. 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. On eviction night, the audience votes to evict one of the nominees.

The season premiered on 17 October 2022, and ran for 162 days, with the season ending on 27 March 2023.

Marcos Ginocchio was crowned the winner of the season, with Juan Ignacio Castañares finishing as runner-up and Julieta Poggio in third place.

On 26 March 2023, Gran Hermano was renewed by Telefe for an eleventh season to premiere in late 2023.

Format
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. The HouseGuests are sequestered with no contact with the outside world. During their stay, the HouseGuests share their thoughts on their day-to-day lives inside the house in a private room known as the Diary Room. Each week, the HouseGuests compete in competitions in order to win power and safety inside the house. At the start of each week, the HouseGuests compete in a Head of Household (abbreviated as "HOH") competition. The winner of the HoH competition is immune from eviction and selects another HouseGuest to be saved for eviction. On eviction night, the audience vote to evict one of the nominees, and the nominee with the most votes is evicted from the house.

HouseGuests
A total of 18 HouseGuests moved into the house on Day 1 (17 October 2022), with the last two new HouseGuests moving into the house on Day 60 (15 December 2022). Former evicted HouseGuest Juliana Díaz returned to the house on Day 66 (21 December 2022), and other three evicted HouseGuests (Agustín, Daniela and Lucila) returned on Day 71 (26 December 2022).

Relatives
On Day 127 (20 February 2023), relatives from each one of the six remaining HouseGuests that were in competition at the time entered the house.

Voting history
HouseGuests nominate for two and one points, shown in descending order in the nomination box. The four or more HouseGuests with the most nomination points face the public vote.

HouseGuests can also use the Diary Room's Special Nomination, which gives three and two points instead. HouseGuests that use the Special Nomination are marked in orange.

From Weeks 14 through 20, the Power Nomination (fulminante in Spanish) was enabled by Gran Hermano, which consists of the automatic nomination of a HouseGuest, without the ability to be saved by the Head of Household. It could only be used once by each contestant throughout those weeks. HouseGuests that use the Power Nomination are marked in bold.
