عامل نخر الورم ألفا (بالإنجليزية: Tumor necrosis factor alpha)‏ ومختصره (TNFα) ويسمى أيضا كاككتين (بالإنجليزية: cachectin)‏ أو كاككسين (بالإنجليزية: cachexin)‏ هو بروتين إشارة خلوية (سيتوكين) يشارك في عملية الالتهاب في جسم الإنسان.[1][2][3]

حاليا بحذف كلمة ألفا من تسمية عامل نخر الورم ألفا والاكتفاء بتسميته عامل نخر الورم لأن لمفوتوكسين ألفا لم يعد يسمى عامل نخر الورم بيتا.
