Jacques "Jacky" Eeckelaert (born 11 January 1955) is a Belgian automotive engineer who has worked in many categories of motorsport.
At the end of 1999, he was offered a similar role at the Sauber team and two years later returned to the Grands Prix as Kimi Räikkönen's race engineer.
In 2007, he was promoted to Engineering Director, after predecessor Mark Ellis moved to sister team Super Aguri.
Eeckelaert himself then moved to Super Aguri, only for the team to shut down after running out money part-way through the 2008 season.
In November 2012 Eeckelaert moved to the German DTM team Abt Sportsline, where he works as Technical Director.
