Renate Boesler, also referred to as Bösler and later as Gunkel, is a retired East German rower who won medals at European championships between 1963 and 1971. During that time, she became European Champion four times in two different boat classes.

The 1964 European Rowing Championships for women were rowing championships held on the Khimki Reservoir, which is part of the Moscow Canal, in Khimki near Moscow in the Soviet Union. The competition for men had been held the previous month in Copenhagen. The regatta in Khimki was held from 6 to 8 September. Five boat classes were contested. Eleven countries nominated a total of 33 boats for the regatta, which was held over 1,000 metres. Five lanes were available and this meant that in three boat classes, there was only the final: W2x, W4+, and W8+.
