Joachim Halupczok (3 June 1968 - 5 February 1994 ) was a Polish racing cyclist.

He won the silver medal in the team time trial at the 1988 Summer Olympics along with Andrzej Sypytkowski, Marek Lesniewski and Zenon Jaskuła.

In 1989 he became the amateur champion at the 1989 UCI Road World Championships.

In 1990 he signed professional terms and took part in the World Championships in Utsunomiya. He was later diagnosed with cardiac arrhythmia, which meant that he had to quit professional cycling. It was suspected that the cause of his health problems was the use of EPO.

Death

Halupczok died of a heart attack on the way to the hospital, after he collapsed during a warm-up for an indoor football match on 5 February 1994. He was survived by his wife and two children.
