Ein Cardiotoxin ist ein speziell auf den Herzmuskel wirkendes Gift. Funktionell wirkt es wie ein Neurotoxin.
Cardiotoxine finden sich vor allem in Schlangengiften, den Nesselgiften von Nesseltieren und anderen Tiergiften. Die Gifte wirken depolarisierend auf die Zellmembranen der Herzmuskelzellen und führen dadurch zu einer Lähmung deren Resultat ein Herzstillstand sein kann.
