Sister Wives is an American reality television series broadcast on TLC that premiered on September 26, 2010. The show documents the life of a polygamist family, which includes Kody Brown, his current wife Robyn (née Sullivan), and his former wives Meri (née Barber), Janelle (née Schriever), and Christine (née Allred), and their 18 children (1 by Meri, 6 each by Janelle and Christine, 5 by Robyn although 3 were between her and her ex-husband David Preston Jessop). The family began the series living in Lehi, Utah, moved to Las Vegas in 2011, and to Flagstaff, Arizona, in mid-2018.

The Browns have stated they participated in the show to make the public aware of polygamist families and to combat societal prejudices. When the show began, Kody Brown argued that his polygamist arrangement was legal because he was legally married to only one woman, while the three other marriages in the family were "spiritual unions."
