Cœur de verre is the name of the first studio album recorded by the French singer Hélène Ségara.

It was released in 1996, after its first hit single, "Je vous aime adieu", and achieved success in France and Belgium (Wallonia).

In 1996, she was in Paris and met the composer Christian Loigerot who wrote eight tracks of her debut album, Cœur de verre.

French singer Phil Barney, who had already a solo career in France and a hit in 1987, "Un Enfant de toi", participated in the writing of the song "Vivre dans l'éternité", while the brothers Alain and Marc Nacash, who reached number ten on the French Singles Chart in December 1987 with the single "Elle imagine" under the name of Nacash, wrote to her the hit "Les Vallées d'Irlande" (later they also wrote "Parlez-moi de nous" on Ségara's next album, Au Nom d'une femme).

The song "Une Voix dans la nuit" is based on Donna Summer's 1979 hit "On the Radio".
