To describe students critical thinking ability on trigonometric problems, a research was conducted on 30 students (15/16 years old) in West Java, Indonesia. This research is a qualitative descriptive research and data collection technique is written test with 3 description questions. The test results were analyzed using three indicators of critical thinking ability, (1) composing questions with reasons, (2) identifying relevant and irrelevant data of a mathematical problem, and (3) solving mathematical problems with reasons. The results showed that: (1) almost one-third of the number of students can compile the questions with the reasons, (2) more than one-third of students can identify the relevant and irrelevant data of a mathematical problem, and (3) more than one-third of students can solve the mathematical problems with reasons. The average percentage of students on trigonometric problems is 31,86%. Based on the result of research, it is seen that most students do not have good critical thinking ability on solving trigonometric problems.
