Penelitian ini bertujuan untuk mengkaji apakah terdapat hubungan antara parenting stress ibu dengan regulasi emosi anak usia prasekolah. Jenis penelitian ini merupakan penelitian kuantitatif dengan teknik pengujian Korelasi Pearson. Parenting stress ibu diukur menggunakan instrumen Parenting Stress Index - Short From (PSI-SF) dan regulasi emosi anak usia prasekolah menggunakan alat ukur Emotion Regulation Checklist (ERC). Jumlah partisipan pada penelitian ini sebanyak 128 ibu dengan anak usia prasekolah (3 - 6 tahun). Hasil utama penelitian menunjukkan bahwa terdapat hubungan negatif yang signifikan antara parenting stress dengan regulasi emosi anak usia prasekolah. Hal ini menunjukkan bahwa semakin tinggi parenting stress yang dialami ibu, maka regulasi emosi anak usia prasekolah semakin rendah, dan sebaliknya ibu yang cenderung memiliki tingkat parenting stress rendah maka regulasi emosi anak akan semakin baik.
