This study aims to examine the effect of mathematical disposition of junior high school students on mathematical communication skills. This study used a correlation method with a quantitative approach. The subjects in this study were 31 student which is the eighth grade at one of the junior high schools at Bandung. The instrument used consists of a test instrument which is a test of mathematical communication skills with the indicator is forming a mathematical model; arguments based on analysis of images and concepts; and the appearance of conceptual models, such as images, diagrams, tables and graphs and non-test instruments in the form of questionnaires about students' mathematical dispositions. The results of the study show that the mathematical disposition of junior high school students has a positive influence on mathematical communication skills. Students' mathematical communication skills are influenced by mathematical dispositions of 74.5% and 25.5% influenced by other factors beyond students' mathematical dispositions. This shows that the relationship between students' dispositions and its mathematical communication skills is strong enough. Students who have a positive disposition towards mathematical learning tend to be active and can express ideas well. © 2019 IOP Publishing Ltd.
