Bigg Boss (Tamil TV series) season 4

Bigg Boss (Tamil TV series) season 4 was the fourth season of the Tamil-language reality television game show Bigg Boss, based on the Dutch show Big Brother. It premiered on Vijay Television on October 4, 2020, and concluded on January 17, 2021, lasting for 106 days. Kamal Haasan returned as host for the fourth consecutive season.

The season followed a group of contestants, known as housemates, who lived together in a custom-built house isolated from the outside world. They were continuously monitored by live television cameras and personal audio microphones. Throughout their stay, housemates competed in various tasks and challenges designed to test their physical and mental endurance, strategy, and social skills. They were also subjected to public nominations and eliminations, with viewers voting to save their favorite contestants.

A notable difference from previous seasons was the implementation of stricter COVID-19 safety protocols due to the ongoing pandemic. Housemates underwent quarantine and testing before entering the house.

The winner of Bigg Boss (Tamil TV series) season 4 was Aari Arjuna, receiving a cash prize and the title. The runner-up was Balaji Murugadoss. The season was notable for its high viewership and discussions surrounding the contestants' behavior and strategies both within the house and on social media platforms. Other prominent contestants included Rio Raj, Ramya Pandian, and Gabriella Charlton.
