Zusammenfassung:	Provided is a steering control apparatus configured to suppress the occurrence of abnormalities in components in respective systems at the same timing. A first assist torque calculation circuit (50) calculates a first command value (T1a) and a second command value (T2a) based on a steering torque ([tao]1). A first current feedback control circuit (51) calculates a control signal (Sml) by using the first command value (T1a). A second current feedback control circuit (61) calculates a control signal (Sm2) by using the second command value (T2a). When the steering torque ([tao]1) is equal toor smaller than a steering torque threshold, the first assist torque calculation circuit (50) executes calculation so that the first command value (T1a) is larger than the second command value (T2a). After the steering torque ([tao]1) exceeds the steering torque threshold, the first assist torque calculation circuit (50) executes calculation so that the first command value (T1a*) is equal to thesecond command value (T2a
