The International Association for Relationship Research (IARR) is an interdisciplinary organizations that strives to (a) promote advances in the scientific study of personal and social relationships, and (b) encourage collaboration among students, new scholars and experienced scholars. IARR resulted from the integration of two prior organizations (the International Society for the Study of Personal Relationships, the International Network on Personal Relationships) and has worked to maintain the high standards set by each organization.

IARR's members represent a broad range of disciplines, such as family studies, psychology, communication, sociology, child/lifespan development, gerontology, education, clinial work (e.g., counseling, therapy) and anthropology. As a non-profit organization, IARR encourages cooperation among social scientists worldwide and supports the application of research findings in bettering individuals' relationships.

The organization has members from six of the seven continents (there are no members from Antarctica). IARR sponsors two journals (Personal Relationships, Journal of Social and Personal Relationships), a newsletter (Relationship Research News), a book series (Advances in Personal Relationships) and workshops/conferences. In addition, the organization hosts a biennial conference and annual workshops and specialty conferences. Recent conferences have been held in Greece, USA and Brazil.
