Sandra Caldarone (born 15 October 1972), better known as Sandra Kim, is a Belgian singer of Italian descent who won the Eurovision Song Contest 1986 in Bergen, Norway. Her father was an Italian immigrant from Torrebruna in the Province of Chieti in the Abruzzo region of Italy.

At the time of her Eurovision win, she was only 13 years old, making her the youngest winner of the contest, even though the lyrics of her song "J'aime la vie" ("I love life") imply that she is 15; the Swiss petitioned to have the song disqualified after her real age was revealed. This petition ended up failing and Kim went on to win that year's Eurovision Song Contest. Kim also represented Belgium at the Yamaha Music Festival in Tokyo during the autumn of 1986 and sang the title song for the French animated television series Il était une fois... la vie. Kim's pop rock album Make Up was released on 12 May 2011, containing songs written by famous Belgian artists like Salvatore Adamo, Dani Klein (Vaya Con Dios), Ozark Henry, Anthony Sinatra (Piano Club), Jacques Duval and David Bartholomé (Sharko). She also won the first season of the Belgian version of The Masked Singer as “Queen”.

In March 2023, Kim was a guest celebrity judge in the episode A deux c’est mieux of the Belgian French-language reality television series Drag Race Belgique, which was broadcast on Tipik.
