Claudia Maria Poll Ahrens (born 21 December 1972) is a former Costa Rican swimmer who competed in the 200 m to 800 m freestyle events. She is Costa Rica's only Olympic gold-medalist, having won the country's first Olympic gold medals at the 1996 Olympics in the 200 meter freestyle. She is a multiple national record holder in the freestyle events.
Her sister, Silvia, won Costa Rica's first Olympic medal, the silver medal, at the 1988 Games. As of 2021, Claudia and Silvia are the only Costa Ricans to have won a medal at an Olympics. Claudia also competed at the 2000 Olympics, where she won two bronze medals.
Claudia Poll began swimming in 1979 under coach Francisco Rivas and quickly became one of the best in Central America, winning many regional titles.
At the 1996 Atlanta Olympics she won the gold medal in the 200 m freestyle event. The win was the first gold medal for Costa Rica in the Summer Olympic Games. It was a surprising win because she beat the favorite German Franziska van Almsick. Dagmar Hase, also from Germany, won the bronze.
In 2002, she was given a four-year doping ban after a failed test for norandrosterone, a metabolite the steroid nandrolone. Her ban was later reduced by FINA to two years. Poll claimed that the test and sampling methods were flawed and protested her innocence.
At the 2006 Central American and Caribbean Games, she set the Games Records in the 200 and 400 freestyles (2:00.19 and 4:15.01), bettering the time her sister Silvia set at the 1986 Central American and Caribbean Games.
Poll served as a swimming analyst for the U.S. Telemundo network's Spanish-language coverage of the 2012 Summer Olympics in London, though she and most of the Telemundo broadcast crew performed their duties at the network's studios in Hialeah, Florida, accompanied by video provided by Olympic Broadcasting Services.

Claudia’s parents are both German, but they moved to Nicaragua before starting a family. Claudia and her sister Silvia were both born in Managua, Nicaragua, but moved shortly after Claudia’s birth in 1972. Political tensions were rising and after an earthquake that shook the city, the family decided it would be safer to move to Costa Rica.
Claudia graduated in Business Administration from the Universidad Internacional de las Américas, San José, Costa Rica, in 1998. Poll became a mother for the first time on August 8, 2007. Her daughter's name is Cecilia. Claudia's older sister Silvia Poll was also a competitive swimmer who won a silver medal in 1988, Costa Rica's first ever Olympic medal.
