Students' geometric thinking skills can describe students' understanding of geometrical concepts. According to van Hiele, students' geometric thinking skills is divided into five levels, namely Level 0 Visualization, Level 1 Analysis, Level 2 Informal Deductive, Level 3 Deduction, and Level 4 Rigor. The level of students' geometric thinking skills be an indicator of the success of learning geometry. The teacher should be able to analyse the students' geometric skills to help students to improve their geometric thinking skills. The purpose of this study was to describe the geometric thinking skills of 7th grade students of Junior High School in Boyolali, Indonesia. This type of research was quantitative descriptive research. The study was conducted by giving ten questions that correspond to the level of students' geometric thinking skills. The results showed that as many as 26.09% of students were at level 0, as many as 56.62% of students were at level 1, as many as 17.39% of students were at level 2, and no students were able to reach level 3.
