A phobia is an irrational, intense and persistent fear of certain situations, activities, things, animals, or people. The main symptom of this disorder is the excessive and unreasonable desire to avoid the feared stimulus. When the fear is beyond one's control, and if the fear is interfering with daily life, then a diagnosis under one of the anxiety disorders can be made. Phobia is also described as an unreasonable or abnormal fear.

Phobias are a common form of anxiety disorders. An American study by the National Institute of Mental Health (NIMH) found that between 8.7% and 18.1% of Americans suffer from phobias. Broken down by age and gender, the study found that phobias were the most common mental illness among women in all age groups and the second most common illness among men older than 25. Some phobias are generated from the observation of a parent's or sibling's reaction. The observer then can take in the information and generate a fear of whatever they experienced

Phobias are not generally diagnosed if they are not particularly distressing to the patient and if they are not frequently encountered. If a phobia is defined as "impairing to the individual", then it will be treated after being measured in context by the degree of severity. A large percent of the American population is afraid of public speaking, which could range from mild uncomfortability, to an intense anxiety that inhibits all social involvement.
