Arianna Fontana (ITA) is the 500m champion after a photo finish placed her ahead of Choi Min-Jeong (KOR).
Yara van Kerkhoff (NED) finished third in the race.
After the race, the judges penalized Choi for cutting the line promoting van Kerkoff and Kim Boutin(CAN) , to silver and bronze.
This is Fontana’s sixth Olympic medal but her first gold. This is also her third medal in this event, winning a bronze in the 500m in Turin 2006 and a silver in Sochi 2014.
Fontana equals Wang Meng (CHN) for the most medals by a woman in short track speed skating.
Boutin, Elise Christie (GBR), Choi, van Kerkhoff, and Fontana made up the five-racer final.
Boutin was elevated to the final by the judges after a collision in her semifinal.
China, which had won the women’s short track 500m at the past four Olympics, did not have a representative in the final after Fan Kexin and Qu Chunyu were penalized in the semifinals.
Marianne St-Gelais (CAN) and Maame Biney (USA) were the two biggest names eliminated in the quarterfinal stage.
St-Gelais was disqualified for a penalty after a crash.
“Sometimes things go your way and sometimes they don’t,” St-Gelais said to the media. “However, that’s done and I have to think about the other distances. It’s disappointing for sure because I don’t think I deserve this call.”
Biney was unable to recover from a slow start in her race.
“I lost my rhythm throughout the whole race and I couldn’t find it again. Over the next four years, I’m going to try to find that rhythm and just keep going,” Biney said after the race.
