Halina Sylwia Górecka (née Richter, later Herrmann; born 4 February 1938) is a retired Polish and German sprinter.

The Polish team set a world record in the 1964 final, but it was annulled after one teammate, Ewa Kłobukowska, failed a gender test in 1967.

[1][2] In 1964 Górecka became a double champion of Poland: in 100 m and 200 m, adding to her earlier Polish title in the 4 × 100 m relay in 1954.

In 1965, at an international meet in Dortmund, she defected to West Germany and went to Cologne to a friend Reinhold Herrmann.

Her appearance for West Germany at the 1968 Olympic Games in Mexico City did not result in any medals.
