The 2017 Horizon League Women's Soccer Tournament was the postseason women's soccer tournament for the Horizon League. It was held from October 30 through November 4, 2017. The quarterfinals of the tournament were held at campus sites, while semifinals and final took place at Engelmann Field in Milwaukee, Wisconsin. The six team single-elimination tournament consisted of three rounds based on seeding from regular season conference play. The Northern Kentucky Norse were the defending champions, but they were eliminated from the 2017 tournament with a 3–2 loss to the IUPUI Jaguars in the semifinals. IUPUI won the tournament by virtue of winning the penalty shoot-out tiebreaking procedure following a tie with the Milwaukee Panthers in the final.
