What is the role of cultural humility in psychoanalytic supervision? In this article, we address that question. While culture has been recognized as central to supervision practice (e.g., Tummala-Narra, 2004), the psychoanalytic supervision literature remains highly limited in addressing issues related to culture and diversity. In what follows, we present a psychoanalytic supervision perspective that is anchored by the construct of cultural humility. Cultural humility is defined, 10 conceptual/practice guideposts of a culturally humble supervision view are proposed, 2 supervision case examples are described, and some supervision/cultural humility research hypotheses are proposed for possible empirical study. Teaching supervisees about and modeling cultural humility is considered to be preparatory education for the creation of a cultural third. Realizing cultural humility via supervisory interaction involves the opening of a supervisor-supervisee third space whereby cultural meanings and experiences are welcomed and can be explored, examined, and experienced anew. This supervision cultural third ideally becomes a prototype for the supervisee/ patient's own creation of a treatment cultural third.
