Bigg Boss 4 in 2010 was the fourth season of Indian reality TV show Bigg Boss, which aired on Colors from 3 October 2010. This season was longer than its predecessor, Bigg Boss 3 and lasted for 14 weeks (96 days) ending on 8 January 2011. The show was hosted by Salman Khan.
During the launch on 3 October, fourteen hand-picked housemates entered the house located in Lonavla, a hill station, about 100 kilometres east of Mumbai in the Indian state of Maharashtra. Two additional wild card entries were made during the second and third weeks, taking the number of contestants to sixteen. The housemates, considered strangers to each other, spent 96 days (14 weeks) locked up together under the supervision of 32 cameras fitted around the house. Four of the housemates, Ashmit Patel, Dolly Bindra, The Great Khali and Shweta Tiwari, reached the final week, facing public vote. The show ended on 8 January 2011 with the grand finale. Shweta Tiwari emerged as the winner, going away with a prize money of ₹ 10 million, while The Great Khali was announced as the runner-up.
Salman Khan was appointed as the new host for the series.
Devender (Bunty) has been accused of robbery and was on the most wanted list of the Delhi police. Dibakar Banerjee has made a film on him, Oye Lucky! Lucky Oye!, where Abhay Deol played the protagonist. 
According to data available with aMap, a television viewership monitoring agency, the opening episode of Bigg Boss 4 on Colors got a rating of 3.6.

During the first week of the show's airing, activists of Shiv Sena, a political party, started protesting against the inclusion of Pakistani housemates in the show. After being evicted from the house, Rahul Bhatt claimed that Bigg Boss is scripted. In November 2010, the Information and Broadcasting Ministry served a notice on Colors, due to complaints of indecent exposure aired on national television, asking the channel to change the timings of the show from 9:00 pm to 11:30 pm. The channel later got a stay order from Bombay High Court allowing them to continue the telecast of the show during prime time.
