A remaining fuel amount display device including: a fuel gauge; a sensor that detects the remaining fuel amount of the fuel tank; and an electronic control unit that calculates an indication value of the fuel gauge. The electrical control unit calculates the indication value by subtracting a subtraction value from a last indication value when the last indication value is greater than a detected value of the remaining fuel amount. The last indication value is calculated at one time before the indication value. The subtraction value is greater than a latest fuel consumption amount in an interval of the calculation of the indication value and equal to or less than a sum of the fuel consumption amount and a difference between the last indication value and the detected value. The subtraction value becomes larger when a value obtained by comparing the last indication value with the detected value is larger.
