Background and Objectives: Cluttering is a speech fluency disorder in which individuals cannot regulate their speech rate to match syntactic or phonological demands in time. Similar to stuttering, there is currently no known cause for cluttering. Due to low awareness of their disorder, individuals with cluttering often do not seek speech therapy or pursue treatment independently. This lack of awareness has resulted in limited clinical experience among speech and language pathologists, especially younger therapists, regarding assessment and treatment processes for these individuals, despite the theoretical information available in the scientific literature. Therefore, this study aims to examine the speech and language characteristics of a person with cluttering, assess them, and provide a therapeutic plan through a case study format. 
Case Presentation: In this study, the speech and language characteristics of a 34-year-old man who was referred to the clinic with a complaint of speech disorder were evaluated and analyzed. Finally, based on the evaluation results, the diagnosis, prognosis, and treatment recommendations were presented.
Conclusion: This is the first case report of cluttering disorder in Iran. The results, prognosis, and treatment approaches discussed in this article can serve as useful resources for speech and language pathologists.
