A persecutory delusion is a type of delusional condition in which the affected person believes that harm is going to occur to oneself by a persecutor, despite a clear lack of evidence. The person may believe that they are being targeted by an individual or a group of people. Persecution delusions are very diverse in terms of content and vary from the possible, although improbable, to the completely bizarre. The delusion can be found in various disorders, being more usual in psychotic disorders.

Persecutory delusion is at the more severe end of the paranoia spectrum and can lead to multiple complications, from anxiety to suicidal ideation. Persecutory delusions have a high probability of being acted upon, for example not leaving the house due to fear, or acting violently. The persecutory delusion is a common type and is more prevalent in males.

Persecutory delusions can be caused by a combination of genetic (family history) and environmental (drug and alcohol use, emotional abuse) factors. This type of delusion is treatment-resistant. The most common methods of treatment are cognitive behavioral therapy, medications, namely first and second generation antipsychotics, and in severe cases, hospitalization. The diagnosis of the condition can be made using the DSM-5 or the ICD-11.
