A gear shift control apparatus for an automatic transmission includes: a gear-shift-state-determining unit for determining the presence or absence of a gear-shift-determination of the automatic transmission; a gear-shift-time-estimating unit, when there is the gear-shift-determination, for estimating gear-shift-completion-time since the present gear is shifted to another gear and, after that, further shifted to the present gear; a fuel-consumption-estimating unit for estimating a first fuel consumption in the case where the vehicle drives for the gear-shift-completion-time in the present gear and a second fuel consumption in the case where the present gear is shifted to another gear and, after that, further shifted to the present gear; and a fuel-consumption-determining unit for determining validity of the gear shift on the basis of fuel consumptions. A gear-shift-control unit changes the determination of shifting to another gear at the time of the gear-shift-determination in accordance with a determination result of the fuel-consumption-determining unit.
