Obsidyen (ya da obsidiyen), doğal yollarla oluşan volkanik kökenli bir cam türüdür. Lavın hızlıca soğuması ve kristalleşmeye yetecek kadar zaman geçmeden donmasıyla oluşur. Genellikle felsik lav akıntılarının, soğumanın hızlı olduğu kenar bölümlerinde bulunur. Kristal yapıda olmadığından, keskin kıyıları moleküler inceliğe ulaşabilir. Bu özelliğinden ötürü eski çağlarda ok ucu olarak kullanılmış, günümüzde ise cerrahların kullandığı neşterlerin kesici kısımlarında kullanılmaktadır
