Axel Eddy Lucien Jonkheer Merckx (born 8 August 1972) is a Belgian former professional road bicycle racer and the son of five-time Tour de France champion Eddy Merckx. He is currently the team director of UCI Professional Continental team Hagens Berman Axeon.
Born in Uccle, Axel Merckx became a professional cyclist in 1993, winning the Belgian national road race championship in 2000. He repeatedly vowed to make his mark by accomplishing feats that had eluded his father Eddy, such as winning a Tour de France stage at Alpe d'Huez and the Paris–Tours classic. He did not succeed, but competed in eight Tours de France and finished as the highest-placed Belgian rider six times.
During the 2006 Tour, Merckx announced that he signed a new contract for one extra season with Phonak, later renamed iShares. He stated that this would be his last season as a professional road bicycle racer. However, after Phonak announced that it would stop sponsoring the cycling team, Merckx signed a contract with Team T-Mobile, where he had started his professional career.
He created the Granfondo Axel Merckx National Series, with its inaugural event being the Granfondo Axel Merckx Okanagan on 10 July 2011 in Penticton, British Columbia. His father, Eddy, rode in the inaugural event.
His name was on the list of doping tests published by the French Senate on 24 July 2013 that were collected during the 1998 Tour de France then retested in 2004. Merckx was not one of then 18 Riders named as testing positive for EPO but was on a list of 12 named riders whose test results were listed as "suspicious". 
Because his father was made a baron—a personal, hereditary title—in Belgium, Axel Merckx has also been ennobled. He is therefore officially referred to as Ecuyer (in French) or Jonkheer (in Flemish) Axel Merckx. This honorific title is comparable to the British The Honourable, when the untitled person is the offspring of a baronet, earl or viscount.
