Helen Sandy Pflueger (born 14 April 1954) is an American and Kama'aina equestrienne. She has competed successfully in both eventing and dressage, finishing second at the prestigious Badminton Horse Trials in 1981 and competing on the United States Dressage Team at the 1984 Los Angeles Olympics. She competed under the British flag at the World Equestrian Games in Rome 1998 and Aachen 2006 and the European Championships in Arnheim 1998.

She is the daughter of Nancy and James Pflueger, a Kauai landowner, auto dealer, philanthropist and self-made millionaire. On 1 February 1997, Sandy Pflueger married British Olympian and coach of the American Eventing team, Captain Mark Phillips, whose first wife was Princess Anne, the daughter of Queen Elizabeth II. Pflueger coached the US eventing team in dressage, alongside her husband.

The couple lived in England with their daughter, Stephanie (b. 2 October 1997). Pflueger is also stepmother to Peter Phillips and Zara Tindall, the oldest grandchildren of Queen Elizabeth II.

Pflueger was the co-owner of Hawaii's Ka Loko Dam, which collapsed after heavy rain on 14 March 2006, killing seven people. Unlicensed grading operations had been carried out, with the knowledge of the local authorities, who failed to enforce a stop-work order.

It emerged in May 2012 that Capt. Phillips had left his second wife and intended to divorce her having become involved with another woman, Lauren Hough.

In equestrian sport Sandy is still active as an FEI 4* international jury member in dressage and FEI 3* international jury member in eventing. She also coaches several riders and gives clinics worldwide. She was a member of the jury during the 2016 Summer Olympics in Eventing.
