Helen Louise Maroulis (born September 19, 1991) is an American freestyle wrestler who competes in the women's 55-kg and 53-kg categories. She was a gold medalist at the 2015 World Wrestling Championships in Las Vegas, Nevada and a gold medalist at the 2011 Pan American Games in Guadalajara, Mexico. At the 2016 Summer Olympics in Rio de Janeiro, Brazil she became the first-ever American to win a gold medal in women's freestyle wrestling at the Olympic Games.^[1]

Maroulis was born in Rockville, Maryland, the daughter of Paula and Yiannis "John" Maroulis.^[2] Her father is Greek.^[3] She attended Magruder High School for three years, where as a freshman she became the first female wrestler to place at the Maryland state wrestling championships^[4] and also was named Most Outstanding Wrestler of a tournament by pinning the senior boy who had won that title the year before, all on the way to 99 high school career victories.^[5]

She then moved to Marquette Senior High School in Marquette, Michigan and then went to join Missouri Baptist University women's wrestling team in Saint Louis, Missouri, before ultimately transferring to compete for Simon Fraser University in Burnaby, British Columbia, Canada.^[6]

She now trains at the U.S. Olympic Education Center at Northern Michigan University.^[2] Her grandparents emigrated to the United States from the Greek island Kalamos in the 1960s.

Maroulis beat Saori Yoshida 4-1 to win a gold medal at the 2016 Rio Olympics. This was the first Olympic gold medal for the United States in a women's wrestling event.^[7] Maroulis attributes a large portion of her success to the coaching of Valentin Kalika.^[8]

Maroulis won her third consecutive gold medal at the world championships or Olympics defeating Olympic bronze medalist Marwa Amri of Tunisia in the finals of the 58-kilogram/128-pound weight class with an 11-0 technical fall.^[9]

On January 16, 2018, Pooja Dhanda defeated Maroulis in the Pro Wrestling League.^[10][11]

Maroulis was defeated in the first round by fall by Azerbaijan’s Altona Kolesnik, a shocking upset for the defending world and Olympic champion. The defeat has been attributed to a serious head injury (concussion from a tournament in January 2018^[12]). As Maroulis stated in post-match interview “I’m so used to telling someone, hey, don’t touch my head.” The injury was significant enough to cause Maroulis to delay her world team qualifier match, and significantly limited her live sparring prior to the event. It is reported that she was so limited by the injury that she only returned to live practice about 10 days before her rescheduled qualifying series. ^[13]
