This paper talks about emotions in art expression in preschool children. Through the work, theories about emotions and their expression in art expression in preschool children are extended. Also, the developmental stages of children's artistic creation are defined and graphically presented. Since artistic expression is an innate ability to express oneself, it is not learned but develops from the child's potential, that is, in the interaction of the child's inner state and its environment. Although the ability of artistic expression and creation is innate in people, it appears only as a result of the artistic work of an individual. In the development of children, their parents and their environment play a big role, which can stimulate children's artistic creativity in different ways: by activating memories, imagining, directing attention, playing with art materials, confirming. Before all of that, the most important thing is to encourage the child to try and participate in art activities, to encourage the child's interest in exploring and discovering the world, to encourage their curiosity. A child develops cognitively, motorically and physically, but it also develops emotionally from birth. The child develops relationships with himself and his environment. With the help of emotions, the child can signal his needs and wishes to his environment. It is of great importance that the child, in addition to showing emotions, understands and regulates them.
