Marko Aleksejev

Marko Aleksejev (born 14 February 1979) is a retired Estonian high jumper. He was selected to compete for the Estonian squad in the men's high jump at the 2004 Summer Olympics, and also trained throughout his athletic career for Audentese Sport Club in Tallinn, under his personal coach Allan Eleranna. In 2005, Aleksejev recorded his personal best jump at 2.28 m from the International High Jump Meet in Bühl, Germany.

Aleksejev qualified for the Estonian squad in the men's high jump at the 2004 Summer Olympics in Athens. Aleksejev elected to strenuously pass a single attempt at 2.10 and 2.15, until he could not overhaul the 2.20-metre barrier with all three misses, leaving him in a thirty-first place tie with Spain's Javier Bermejo at the end of the qualifying round.
