This study aims to determine the opinions of mathematics teachers studying at the postgraduate level about mathematical creativity and creative problem-solving skills. The case study method, one of the qualitative research methods, was used in the study. The participants of the study comprised 5 mathematics teachers who are 2 master's, 3 doctoral students. A semi-structured interview form was used as a data collection tool in the study. The data of the study were analysed by the systematic analysis method. According to the results, teachers' opinions about creativity were discussed within the scope of "innovation, originality, difference, productivity, imagination" themes. Participants mentioned the instructional (pedagogical) and personal characteristics of a creative teacher. Teachers presented opinions related to mathematical creativity such as providing more than one (different) solution to a problem, solving the problem in different ways, and having a different point of view. While two of the teachers did not think themselves as adequate in mathematical creativity, the others stated that they found themselves creative. Answers to the mathematical creativity problem showed that teachers' creative problem-solving skills were low.
