Rachel Klamer (born 8 October 1990) is a Dutch professional triathlete and member of the National team.
She placed third at the Junior World Championships in 2009.

Klamer, who presently lives in Sittard, entered the national and international stage in 2008 when she won both the National Triathlon Championships (Junior) in Aalsmeer and the Duathlon Championships (Junior) in Oss, placed 4th in the European Junior Cup at Holten, and, at the age of 17, also started to compete in the elite category, placing 10th in the British Corus Elite Series.

In 2009, she won the silver medal at the European Triathlon Championships in Holten (Junior) and the bronze medal at the Grand Final of the Dextro Energy World Championship Series (Junior).
As a junior at the age of 18, she took part in two Premium European Cups and achieved top placements among the world elite triathletes.
In Alanya, she won the gold medal, and in Eilat she placed fifth, hampered by technical problems with the bicycle chain.

Preparing for the Olympic Games in 2012, Klamer is supported by the club Pro Triathlon founded in 2008 and seems to concentrate exclusively on international events.
In fact, her name does not appear in the National Triathlon Ranking of 2009
 but she won the 3000m National Championships and in 2010 she is also sponsored by the triathlon section of the German club Krefelder Kanu Klub which she represents in the German championship series Bundesliga in 2010.

In French media, Klamer was announced to take part in the 2010 circuit of the prestigious French Club Championship Series Lyonnaise des Eaux representing the club Brive but she did not compete in any of the five triathlons.

Klamer is also part of the Dutch running club, LAAC Twente, for which she won a local German running competition in 2008 alongside her father, Marcel, and her mother, Karin.
This was the year of her breakthrough, when she still lived in Denekamp.

She competed for the Netherlands at the 2012 and 2016 Summer Olympics, finishing in 36th and 10th position respectively.

In 2015, she won the silver medal in the women's triathlon event of the inaugural European Games in Baku, Azerbaijan.
