According to the search results, only three Bachelorettes have won Dancing with the Stars. They are:

• Kaitlyn Bristowe, who won on season 29 in 2020 with her partner Artem Chigvintsev.
• Hannah Brown, who won on season 28 in 2019 with her partner Alan Bersten.
• Melissa Rycroft, who won on her second appearance on the show in 2012 with her partner Tony Dovolani.

Its worth noting that not every Bachelorette who has competed on the show has won. For example, Trista Sutter finished in sixth place.
