A method for controlling a coasting drive of an environmentally friendly vehicle includes: calculating a coasting velocity of the environmentally friendly vehicle at a deceleration event point based on a target coasting distance up to the deceleration event point and a gradient at the deceleration event point; calculating a control target velocity of the environmentally friendly vehicle based on a target velocity of the environmentally friendly vehicle at the deceleration event point and the calculated coasting velocity; and determining control torque to adjust a velocity of the environmentally friendly vehicle to the target velocity to be output to a powertrain of the environmentally friendly vehicle based on the calculated control target velocity.
