Penelitian ini bertujuan untuk mengetahui tingkat self-efficacy, tingkat prestasi, serta pengaruh self-efficacy terhadap prestasi atlet Taekwondo Kyorugi DKI Jakarta. Metode penelitian menggunakan kuantitatif korelasional dengan melibatkan 100 atlet Taekwondo Kyorugi DKI Jakarta yang dipilih melalui teknik purposive sampling. Data self-efficacy dikumpulkan menggunakan instrumen Self-efficacy Scale (SES), sedangkan data prestasi diperoleh dari rekap perolehan medali atlet periode 2023-2026. Karena data tidak berdistribusi normal (uji Kolmogorov-Smirnov dan Shapiro-Wilk), analisis hubungan menggunakan korelasi Spearman’s rho dan regresi sederhana. Hasil menunjukkan mayoritas atlet (60,00%) berada pada kategori self-efficacy sedang dan 28,00% kategori tinggi, dengan rata-rata skor self-efficacy sebesar 71,30. Atlet meraih rata-rata 11,88 medali selama periode penelitian. Uji korelasi Spearman’s rho menunjukkan hubungan sangat lemah tidak signifikan antara self-efficacy dan prestasi atlet (rho = 0,018; p = 0,862), diperkuat oleh hasil regresi sederhana yang juga tidak signifikan (R Square = 0,001; F = 0,093; p = 0,760). Simpulannya, self-efficacy tidak berpengaruh signifikan terhadap prestasi atlet Taekwondo Kyorugi DKI Jakarta, kemungkinan karena ketidaksesuaian (nonconcordance) antara pengukuran self-efficacy pada satu titik waktu dengan data prestasi yang bersifat akumulatif jangka panjang, serta dominannya faktor fisik, teknik, dan taktik. Meskipun demikian, penguatan aspek psikologis tetap relevan sebagai bagian program pembinaan prestasi atlet, khususnya bagi atlet dengan self-efficacy rendah.
