Allison Halverson

Allison Halverson (, ; born 9 September 1992) is an Armenian-American heptathlete and decathlete. She was the 2014 NCAA Division I Outdoor Track and Field Championships heptathlon runner-up for the San Diego State Aztecs track and field team, and she was the inaugural world decathlon champion in 2024. Halverson won the 2010 AAU Junior Olympic Games heptathlon before enrolling at San Diego State University.

Armenia Halverson applied for an Armenian passport during the 2020 season in part to improve her chances of competing in the 2020 Summer Olympics.

Nonetheless, she set the country's national records in the 100 metres hurdles and heptathlon in 2021. She was 13th at the 2021 Texas Relays and 14th at the Multistars meeting.

Halverson lost six pounds of weight while stressed about whether she would compete in the Paris Olympics. She saw promotion for the Women's Decathlon World Championships and decided to enter following the news that she was left off the Olympic team again. She had to learn two new events, the discus throw and pole vault, in only three weeks before the competition. In April 2022, she gave birth to a son and required a blood transfusion due to hemorrhaging and fainting. As part of her appeal to be allowed a transfer of allegiance to Armenia, Halverson said she wanted to start a family and could not wait the three-year maximum application period due to fears of birth defects from a higher maternal age.
