Rönninge Show Chorus is an all-female a cappella and barbershop chorus based in Rönninge, Salem Municipality, just south of Stockholm. Founded in 1983 by Britt-Helene Bonnedahl and now directed by Anna Alvring, the choir has grown to around 100-155 members and is affiliated with Sweet Adelines International. The chorus has won the SAI International Chorus Championship three times - in 2013, 2016 and 2019 - and has never placed lower than 6th in the world at that competition. Each December they co-produce the Stjärnjul Christmas show, a Stockholm tradition since 1993 that has drawn over 200,000 visitors in total.
