Gilles Valere Jacque Elseneer (born 6 March 1978 in Brussels) is a retired professional tennis player from Belgium. He is mostly known for his grass court game, and has achieved his best results on this surface, including a quarterfinal appearance at 's-Hertogenbosch in 2001.
He reached his career-high singles ranking of World No. 97 in July 2004. This was arguably the strongest year of his career, in which he reached the second rounds of the French Open (l. to Gustavo Kuerten) and Wimbledon (l. to Ivo Karlovi?), and won the challengers of Heilbronn and Sarajevo.
He is now coaching and teaching tennis within his father's tennis academy (royal tennis club de Belgique) in Brussels.
