Survivor 1 is the first season of the popular Tamil-language reality show Survivor Tamil. The show is hosted by actor Arjun Sarja.^[1] The show was shot in a remote island in Zanzibar in the country of Tanzania east of Africa, with 18 celebrity contestants known as "castaways". The show was premiered on 12 September 2021 on Zee Tamil and uncut episodes were uploaded on Zee5.^[2][3] The season also featured interviews with the eliminated contestants on Zee5. The show ran for 91 days. The prize money for the winner was ₹1 crore (US$1,34,000).

The elimination process of the show was similar to most other international versions of format, where contestants had to vote each other out. The show followed a similar format to what was shown on the American season called Survivor: Redemption Island, where once the castaway is voted out by the other contestants, they will be sent to a separate island called Moondram Ulagam where they will be asked to compete in a challenge. If they lose the challenge, they will be eliminated from the game. If they win the challenge, they will stay in the game. On the final day, the eliminated jury members will vote for the winner out of the top three finalists. After winning a narrow vote of 4-3-0, Vijayalakshmi Feroz became the winner of the first season while Saran Shakthi was announced as the runner up and Vanessa Cruez emerged as the 2nd runner up respectively.^[4][5][6][7]

Overall 18 contestants appeared in the season as castaways.^[9]

The Total Votes is the number of votes a castaway has received during Tribal Councils where the castaway is eligible to be voted out of the game. It does not include the votes received during the final Tribal Council.

After a castaway is voted out of tribal council they are sent to Moondram Ulagam also known as Third Island. each castaway there will need to win a challenge each week until 1 castaway is eventually sent to merger and resume their game in the main island. If a castaway loses a challenge they will be OUT of the island and game permanently. On Day 50 the Moondram Ulagam finally shut down and the remaining castaways merged into the main game castaways again. On Day 56 the Moondram Ulagam was opened again.

• The castaways names are all in order from who got out of the island.

Although the main format is the same, this season introduced several notable differences from the American version of Survivor:

• Filming length: This season is filmed over 90 days, compared to the 39-day length of most American seasons.
• Airing format: This season airs daily with a focus on a task or tribal council. The American version largely produces one episode for every 1 day, culminating in an elimination; This season has 100 episodes. The first episode of the week features the Leader selection for the tribes, Reward and Immunity challenges, while the second featured Island of the Dead (Moondram Ulagam), battle and Tribal Council.
• Island of the Dead (Moondram Ulagam): A secluded area where voted out contestants competed against each other in duels to remain in the game. When only three contestants remained in the main game, the winner of the final Island of the Dead duel returned to the game. This twist has been used in other international versions of Survivor, and later appeared in the American version as Redemption Island.

Daily after the airing of the episode on television, Zee5 releases Survivor Uncut, which provides the unseen events or footage taken place that wasn't aired on television, which has a longer episode running time. Usually the uncut versions are 2 hr long rather than 45 mins on TV.
