A control apparatus for a hybrid vehicle that can improve the fuel consumption ratio while providing a good drivability is provided. It is determined whether the temperature of a catalyst in an exhaust system is equal to or below a predetermined temperature, and if this condition is satisfied, a Wide Open Throttle determination degree of throttle opening value for determining whether to carry out the Wide Open Throttle control is looked up in a table. Next, it is determined whether a degree of throttle opening is above the Wide Open Throttle determination degree of throttle opening value, and if this condition is satisfied, it is determined whether a remaining battery charge is equal to or above one within the normal use region. If this condition is satisfied, it is determined whether an engine speed is equal to or above a degree of throttle opening Wide Open Throttle prohibiting upper limit engine speed value. If this condition is satisfied, it is determined whether the value of a subtraction timer is zero, and if it is not zero the increase in the amount of fuel is prohibited.
