<onlyinclude>The seventh season of Gran Hermano Argentina started on November 2, 2011 on Telefe. The show's length was approximately five months, finished on April 16, 2012. The prize has been increased to AR$1,000,000 (USD235,000) which will be reduced according to how many times a housemate is nominated. The show is hosted by Jorge Rial, who has hosted the show since 2007, until January 13, 2012 when he left the show. Rial was replaced by Mariano Peluffo, who hosted Gran Hermano spinoff shows.
It became the longest series ever produced of any Big Brother show in the Americas with 164 days. All four finalists (Rodrigo, Walquiria, Jorge and Alex) also became the contestants in the continent with the most survived days in a single series. Rodrigo Fernandez became the winner, at age 19 became the youngest person to ever win the Argentinian series.
Also, this was the last series to air in Telefe, until 2022 when the network took over the format once more and greenlit the show's tenth civilian season.</onlyinclude>
