The article examines the peculiarities of the implementation of interdisciplinary connections in the lessons of fine arts in elementary school, in particular, the concept of «interdisciplinary connections» is substantiated, the levels of interaction of educational subjects are outlined (surface interaction, the influence of one discipline on another, the interrelationship of disciplines). A comparative characterization of interdisciplinary connections and integration in fine arts lessons in elementary school was carried out. Functions (educational, educational, developmental, didactic, integrative, constructive, psychological), types of interdisciplinary connections (content-informational, operational-activity, organizational- methodical) and types of interdisciplinary tasks (knowledge, activity, value-oriented).
 The implementation of interdisciplinary connections in fine arts lessons contributes to the holistic display of educational material, activating younger students to study. Intersubject connections act as an element of integration, relying on knowledge from other educational fields, but in a combination of no more than three in one lesson, and precisely with the main subject in the lesson - visual arts, all other educational subjects are secondary. Since fine art integrates the knowledge of different fields, in such lessons it is possible to realize interdisciplinary connections with music, mathematics, Ukrainian language and literary reading, lessons "Design and technologies", computer science and lessons "I explore the world" (natural, social and health preservation, civic and historical educational fields).
