Provided is a steering controller configured to reduce, as much as possible, the occurrence of switching of a switching device from an interruption state to a transmission state when executing a process for suppressing a steering wheel from being operated such that a steering angle exceeds an upper limit value. In a state where power transmission from the steering wheel to steered wheels is interrupted, a maximum value selection processing circuit (M36) outputs a maximum value (¸e), out of a steered angle (¸p) and a steering angle (¸h), to a limiting reaction force setting processing circuit (M10b) When the absolute value of the maximum value (¸e) has become equal to or larger than a limitation start threshold value (¸1), the limiting reaction force setting processing circuit (M10b rapidly increases a limiting reaction force (Fie). An operation signal generation processing circuit (M26) controls a reaction-force motor to achieve a reaction force command value (Trqr*) corresponding to the limiting reaction force (Fie). When the absolute value of the maximum value (¸e) has become equal to or larger than an engagement threshold value (¸2), a clutch is engaged to transmit a reaction force from the steered wheel-side to the steering wheel.
