An apparatus for determining connection of a trailer includes: a voltage applying unit configured to apply a test voltage to a lamp, provided in a trailer, through a driving voltage supply line according to a lamp check signal, the driving voltage supply line being a line through which a driving voltage is supplied from a vehicle to the lamp; and a control unit configured to determine whether the vehicle and the trailer are connected to each other, based on a voltage applied to a connection detection resistor, provided in the voltage applying unit, by the applied test voltage. A magnitude of current, flowing to the lamp when the test voltage is applied, is smaller than a magnitude of current flowing to the lamp when the driving voltage is applied.
