Thomas Wessinghage (born 22 February 1952) is a German former middle- and long-distance runner who won the 1982 European Championships' final over 5000 metres beating the British world-record holder David Moorcroft. As he was already 30 years old at the time, and had been an international-level runner for a decade, this victory was a long-awaited one for him. He was in top form, having set a European record at 2000 metres shortly before the Championships, and because he was the fastest 1500-metre runner in the final, having run that distance in 3 minutes 31.6 seconds in 1980. Shortly after he started his final sprint with over 250 metres to go, Wessinghage moved into a decisive lead, stretching it into five metres by 4800 metres and almost doubling it by 4900 metres.

In 1980, he set a German record of 3:31.58 min over 1500 metres which stood for 45 years. In the same race Steve Ovett from the UK set a world record of 3:31.36 min. He was married to former Olympian Ellen Tittel. Wessinghage missed a great chance of winning an Olympic medal that year because West Germany joined the United States-led boycott. He was unlucky also in the other Olympic years of his competitive career: he was eliminated in the 1500-metre heats in the 1972 and 1976 Olympics, and he was injured in a race before the 1984 Olympics.

In the 1983 inaugural World Athletics Championships, he was among the favourites to win the 5000-metre title, but for some reason he could not accelerate enough when it mattered the most - during the final lap - despite running at a steady rhythm earlier in the race. Accordingly, he dropped from third to sixth during the last lap, and lost to the winner, Ireland's Eamonn Coghlan, by almost four seconds.

His last major competitive race was in the 5000-metre qualifying heats of the 1986 European Athletics Championships in Stuttgart. In that race, he failed to advance to the final.
