Abstract Background: the prevalence of pregnancy anxiety varies in the different trimesters of pregnancy with high levels in the first and third trimesters. Anxiety in pregnancy is a strong predictor of poor birth processes and infant outcomes. Methods: This study uses quantitative research with quasi experimental / quasi experimental approaches and one group design pre and post test design with group control. This research will use the Hamilton Anxiety Rating Scale (HARS) method. Results: There is a significant difference (p = 0.004 <∝) the average level of anxiety in the control group before (16.5 ± 0.80) and after observation (18.17 ± 1.03) this means that Yoga exercises can reduce anxiety levels in third trimester pregnant women. In the control group (n = 12) there was no negative rank anxiety level which meant that there was no person with an anxiety level before greater than after. Furthermore, a positive rank indicates 10 which means there are 10 pregnant women with anxiety levels after being higher than before or in other words there are 10 pregnant women who have increased anxiety in the third trimester. Conclusion: There is a significant difference (p = 0.004 <∝) the average level of anxiety in the control group before (16.5 ± 0.80) and after observation (18.17 ± 1.03), so it can be concluded that prenatal yoga reduces anxiety levels before and after treatment.
