William "Jimmy" Hartwig (born 5 October 1954) is a German former professional footballer who played as a defensive midfielder.

He also earned two caps for the West Germany national team,[3] making him only the second non-white player (after Erwin Kostedde) to achieve this feat.

He recounted a childhood full of poverty and anti-black racism, with only his German mother as support; his biological African American father never took care of him.

[5] In 2021, he featured in Schwarze Adler [de], a documentary detailing the experiences of Black players in German professional football.

[7] Despite his opposition against anti-black racism, he was criticized for using the word "ching chang chong" in his commentary and then bowing, which was perceived as racist against East Asians, on WELT-TV for the 2022 FIFA World Cup.
