Introduction: Actinomycosis is a systemic chronic bacterial infection caused by Actinomyces Israelii, an anaerobic organism normally resident in the human mouth. However, the actinomycosis of the larynx is very rare, and only about ۱۵ cases have been reported in the literature so far. Most of the cases reported occurred in patients who had previously undergone radiotherapy for laryngeal cancer. Case Report: Here we report a case of actinomycosis of the larynx in a ۱۴-year-old shepherd boy who was not immunocompromised but had a history of tooth extraction two months prior to admission to the hospital and severe laryngitis one year prior to admission. Conclusion:        Laryngeal actinomycosis might be related to poor oral hygiene and mucosal barrier disruption, as well as to being immunocompromised.
