The 2020 Union Omaha season was the first season in the soccer team's history, where they competed in the third division of American soccer, USL League One, the second season of that competition. Union Omaha played their home games at Werner Park, located in Papillion, Nebraska, United States. Union Omaha finished the regular season in second place to qualify for the USL League One final to take place against Greenville Triumph, however the game was canceled due to an outbreak of COVID-19 on the Union Omaha roster.
