Arnaud-Sylvain-André Merklé (born 25 April 2000) is a French badminton player from Staffelfelden. He was the boys singles European Junior Champion in 2018, and also part of the national junior team that clinched the mixed team title in 2017 and 2018. He participated at the 2018 Summer Youth Olympics in Buenos Aires, Argentina, and reached the boys' singles bronze medal match losing to Kodai Naraoka of Japan in the rubber game.
In 2022, Merklé reached his first BWF World Tour final at the Syed Modi International. The final match between Merklé and his compatriot Lucas Claerbout was called off after Merklé tested positive for COVID-19. Both players were later awarded as runner-up with 5.950 ranking point.
