Subjective well-being (SWB) remaja dapat terganggu akibat pandemi COVID-19. Tujuan penelitian ini adalah untuk menguji kontribusi kecemasan, traits kepribadian, dan persepsi terhadap dukungan sosial (perceived social support/PSS) terhadap SWB remaja pada masa pandemi COVID-19 di Indonesia. Partisipan penelitian ini adalah 313 orang remaja (254 perempuan dan 59 laki-laki, usia 13-18 tahun) yang diperoleh secara daring dengan convenience sampling. Penelitian menggunakan alat ukur Satisfaction with Life Scale, Scale of Positive and Negative Experiences, Generalized Anxiety Disorder 7, The Big Five Inventory, dan Multidimensional Scale of Perceived Social Support. Data dianalisis menggunakan regresi hirarki berganda. Hasil menunjukkan bahwa kecemasan, traits kepribadian, dan PSS secara bersama- sama berkontribusi terhadap SWB, kepuasan hidup (life satisfaction/LS), afek positif (positive affect/PA), afek negatif (negative affect/NA). Kecemasan, extraversion, neuroticism, dan PSS dari keluarga dan teman berkontribusi terhadap SWB. Neuroticism, PSS dari keluarga dan teman berkontribusi terhadap LS. Extraversion, openness to experience, dan PSS dari keluarga dan teman berkontribusi terhadap PA. Kecemasan, neuroticism, openness to experience, dan PSS dari keluarga berkontribusi terhadap NA. Agreeableness, conscientiousness, dan PSS dari figur signifikan tidak berkontribusi terhadap SWB (LS, P A, NA). Hasil penelitian ini dapat dimanfaatkan untuk menyusun intervensi psikologis bagi remaja dan psikoedukasi bagi orangtua guna meningkatkan SWB remaja pada masa pandemi.
