Reading and speaking are two important skills to be mastered. A variety of information that obtained from reading can be understood by the readers, and then they can share the information through speaking. This research aimed to find out the correlation between students' reading comprehension and their speaking skill in Explanation Text at SMA Negeri 2 Bukittinggi. This research was conducted by using a correlational research design. The population of this research was 142 students, divided into 4 classes in XI MIPA. The sample for this research was 36 students from class XI MIPA 3, which was taken using the cluster random sampling technique. The data were collected by using two types of tests, namely a reading comprehension test and an oral presentation. Those tests were conducted to determine the students’ reading comprehension and their speaking skill. Then, the data were analyzed by using the Pearson product moment formula. The analysis consisted of two methods: manually and by using the SPSS 21 program. The results show that there was no correlation between students' reading comprehension and speaking skill because the value of rxy = 0.1360 was smaller than the r-table (significant value of 0.05) = 0.3291. It is considered that the hypothesis was rejected and there was no correlation between students' reading comprehension and their speaking skill. Therefore, if students’ reading comprehension scores are high, it does not mean that their speaking scores are high, and vice versa.
