Yann Domenech (born March 17, 1979, in Valréas) is a retired French long jumper.

[1] Representing his nation France at the 2004 Summer Olympics, Domenech registered his best jump at 8.28 m from the Lyon-Parilly Athletics Meet in Vénissieux two months before the Games.

[2] Throughout his career in track and field, Domenech trained for AC Bourg Saint Andéol in Pierrelatte, under his personal coach Christian Branchereau.

[2][3] During the prelims, Domenech spanned his opening legal jump at 7.56 m, until he smoothly extended it to 7.73 m on his second attempt.

Since his third leap produced a cautious foul, Domenech finished only in twenty-eighth out of forty-one athletes, and did not advance past the qualifying round.
