Sandra Diaz-Twine (born July 30, 1974) is an American television personality who became known for her appearances on the reality game show Survivor.

[2] She also competed for a 5th time on the Blood V Water edition of the Australian version of Survivor with her daughter Nina, which premiered in Australia on January 31, 2022.

[3] She was born in Stamford, Connecticut and for a time served in the United States Army as a chemical repair specialist and later an office administrator.

She lives in Fayetteville, North Carolina with her husband Marcus, a career soldier, and her two children, while working as a secretary for a law firm.

Diaz-Twine was the first person to sit out of a challenge and the first to raid on Morgan's camp as part of the reward, where she not only took their tarp, but sabotaged their shelter.

When Drake lost the sixth immunity challenge, the originally-targeted Shawn Cohen was saved when Diaz-Twine turned the alliance against Dunn for instigating an attempted blindside of Boneham.

In a game-changing move, Diaz-Twine, Boneham, and Hastie, unsure about whether to send home Cohen, the last minority alliance member left, or Fairplay, who betrayed them previously together with Dunn, asked them to publicly campaign for their spot.

As the tribes merged into Balboa at 5–5, the Drake tribe, with the help of outcast Roberts, was able to sway Morgan outcast Lillian "Lil" Morris to vote with them, controlling the game and subsequently voting out Morgan leaders Andrew Savage and Ryan Opray.

At the Final Five, Johnson was the next target of Roberts and Fairplay, but Morris started to have suspicions about her alliance (which would prove true eventually).

Roberts made a potentially fatal error by inviting Dalton on his reward trip, leaving the three women, including an angered Morris, together back at camp, sparking a last minute scramble to break the bond between the two guys, eventually voting out Roberts for the second time in the game.

In the Final Three endurance immunity challenge, Morris won and chose to eliminate Fairplay, an error that led to Diaz-Twine's ultimate win.

During her final statements at Tribal Council, Diaz-Twine described her strategy as being the one people would come to if they needed one more vote to oust someone ("anyone, as long as it ain't me").

In Episode Three, when the Villains faced their first Tribal Council, Diaz-Twine stuck with her strategy from Pearl Islands of "anyone, as long as it ain't me."

Despite previously appearing to be in a comfortable six-person alliance, by Episode Eight, she found herself on the outs of her tribe alongside Courtney Yates of Survivor: China.

Despite the pair being considered the weakest on the tribe, Diaz-Twine convinced Russell Hantz that Benjamin "Coach" Wade was against him, and she and Yates survived elimination at Tribal Council.

On May 16, 2010, Diaz-Twine received six jury votes from Yates, Heroes tribe members Thomas, Amanda Kimmel, Candice Woodcock, Boneham and Colby Donaldson to Shallow's three and Hantz's zero to win the game.

The day after Eastin's elimination, Diaz-Twine made an alliance with Survivor: Cagayan winner Tony Vlachos on the basis that they were both major threats.

She and Vlachos pulled in Aubry Bracco, Caleb Reynolds, and Malcolm Freberg, and thus the alliance of five seemed to control the nine-person Mana tribe.

Diaz-Twine gathered her troops; she spoke to those who were on the outs of the alliance of big threats, namely Hali Ford, Jeff Varner, Michaela Bradshaw, and Robertson.

Nuku had an early lead due to Varner's proficient communication skills, but he ultimately lost the challenge at the table maze stage.

After Tribal Council, Diaz-Twine made clear that Bracco was next on her list, since she had failed to get with the rest of the Manas during her time in the game.

As she explained to the other players and in confessions to the camera, she knew she had little chance to win any physical challenge and did not want to face the misery and harsh conditions on the Edge of Extinction.

As a result, she decided to raise the flag and permanently leave the game shortly after her arrival, the only player in the season to do so, and forfeiting her opportunity to be on the jury.

In 2013, Diaz-Twine was in the audience of an episode of Dr. Phil to support her friend and fellow Survivor winner, Todd Herzog, who was struggling with alcoholism.
