'''Pathological jealousy''', also known as '''morbid jealousy''', is a [[psychological disorder]] characterized by a pervasive preoccupation with the belief that one's spouse or romantic partner is being unfaithful, despite the absence of any real or substantiated evidence.<ref name="Kingham" /> The condition encompasses two primary clinical subtypes: [[obsessional jealousy]] and [[delusional jealousy]], the latter also referred to as [[Othello syndrome]].<ref>{{Cite journal |last1=Zheng |first1=Xiaoxiao |last2=Kendrick |first2=Keith M. |date=2021-04-20 |title=Neural and Molecular Contributions to Pathological Jealousy and a Potential Therapeutic Role for Intranasal Oxytocin |journal=Frontiers in Pharmacology |volume=12 |doi=10.3389/fphar.2021.652473 |doi-access=free |issn=1663-9812 |pmc=8094533 |pmid=33959017}}</ref>

Obsessive jealousy is generally classified as a subtype of [[obsessive-compulsive disorder]], reflecting recurrent, intrusive thoughts and compulsive behaviors related to concerns about infidelity.<ref>{{Cite journal |last1=Ahlen |first1=Johan |last2=Ghaderi |first2=Paulina |last3=Boyaci |first3=Rebecka |last4=Mataix-Cols |first4=David |date=2023 |title=Development and Initial Psychometric Evaluation of the Obsessional Jealousy Severity Scale |url=https://www.bjp.org.br/details/2263/en-US/development-and-initial-psychometric-evaluation-of-the-obsessional-jealousy-severity-scale |journal=Brazilian Journal of Psychiatry |volume=45 |issue=1 |pages=85–86 |doi=10.47626/1516-4446-2022-2657 |pmc=9976912 |pmid=35809239}}</ref> In contrast, delusional jealousy is recognized as a subtype of [[delusional disorder]], involving fixed, false beliefs concerning a partner’s infidelity that are resistant to reason or contrary evidence.<ref name="Kingham" />
