Penelitian ini bertujuan untuk menganalisis permintaan dan penawaran ubi kayu di Provinsi Sumatera Utara. Data yang digunakan berupa data sekunder, yang diperoleh dari Badan Pusat Statistik (BPS) Sumatera Utara, Dinas Tanaman Pangan dan Holtikultura Provinsi Sumatera Utara dari tahun 1990-2019. Metode analisis yang digunakan adalah persamaan simultan dengan variabel dependen permintaan dan penawaran ubi kayu dan variabel independen berupa harga ubi kayu (HA), jumlah penduduk (JP), pendapatan perkapita (PPK), luas panen (LP), dan harga pupuk (HP). Data diolah menggunakan Eviews 10.Hasil penelitian menunjukkan HA, PPK, dan JP secara serempak berpengaruh signifikan terhadap permintaan ubi kayu. HA, PPK, dan JP secara parsial berpengaruh positif dan signifikan terhadap permintaan ubi kayu. Dan HA, LP, dan HP secara serempak berpengaruh positif terhadap penawaran ubi kayu. LP secara parsial berpengaruh positif dan tidak signifikan terhadap penawaran ubi kayu sedangkan HA dan HP secara parsial berpengaruh positif dan signifikan terhadap penawaran ubi kayu di Provinsi Sumatera Utara.
