The population of this study was all students of class VIII of SMPN 1 Southwest Praya with the study sample used was the entire population taken with saturated sampling technique. Data collection techniques in this study used self confidence questionnaire instruments and mathematical communication skills tests. Data were analyzed using Microsoft Excel 2013 software with Pearson product moment correlation analysis technique. The results of data analysis show that self confidence and mathematical communication skills are included in the level of strong relationships and have a positive relationship, meaning that if self confidence is good, then mathematical communication skills are also good, and vice versa if self confidence is lacking, then mathematical communication skills are also lacking.
