A steering control device is configured to control a steering device that changes a transmission ratio between an operation angle of an operation member and a steering angle of a steerable wheel. The steering control device includes: communication lines for transmitting vehicle speed information; and calculators communicably connected to each other and individually connected to the communication lines. Each calculator calculates the transmission ratio based on the vehicle speed information received via a corresponding one of the communication lines and determines whether the received vehicle speed information is valid. When at least one of the calculators determines that the vehicle speed information is not valid, each calculator changes control for calculating the transmission ratio from a vehicle-speed responsive control in which the transmission ratio is calculated based on the vehicle speed information to a specific control in which the transmission ratio is calculated not based on the vehicle speed information.
