The type of research used is quantitative correlation. The population is all class VII while the sample is taken using purposive sampling technique. So the sample is 30 students where 15 students are class VII A and 15 class VII B. Theinstrument used is a questionnaire and has been tested for validity and reliability. The test results of the two variables are the validity test of rcount>rtable which means valid and the reliability test of variable X is 0.924> 0.70 and Variable Y is 0.902>0.070 which means reliable. The results of the study where the hypothesis H1 was accepted and H0 was rejected with a sig (2-tailed) value of 0.000>0.005, person correlation 0.837 < 0.361, and r-square 0.700. This means that the professional competence of teachers has a positive influence on students' interest in learning by 70%.
