Laurentia Tan Yen Yi is a United Kingdom-based Singaporean Paralympic equestrienne. Tan developed cerebral palsy and profound deafness after birth, and moved to the United Kingdom with her parents at the age of three. She took up horse riding at age of five years as a form of physiotherapy. She subsequently completed her A-levels at the Mary Hare Grammar School, a residential special school for the deaf, and graduated with an honours degree from Oxford Brookes University in hospitality management and tourism.
In March 2007, the Riding for the Disabled Association Singapore (RDA) invited Tan to join the Singapore team for the World Para Dressage Championships at Hartpury College in Hartpury, Gloucester, in England in July that year. At this event, her first international competition, she did well enough to qualify for the 2008 Paralympic Games. In September 2008, at the Hong Kong Olympic Equestrian Centre at Sha Tin, she achieved bronze medals in the Individual Championship and Individual Freestyle Tests (class IA). These were Singapore's first Paralympic medals and Asia's first equestrian medals at the Paralympic Games. Tan was conferred the Pingat Bakti Masyarakat (Public Service Medal) by the President of Singapore at a ceremony at the Istana Singapore on 20 September 2008.
