The present invention provides a hybrid vehicle driving system which can implement sufficient lubrication while a vehicle is being driven. A hybrid vehicle driving systemof the invention includes a lubrication pumpwhich is connected to a first input shaftand which is adapted to lubricate a transmissionand a lubricated state determination unitwhich determines a lubricated state of the transmission. When the lubricated state determination unitdetermines that lubrication is necessary, the first input shaftis rotated by an electric motorso as to drive the lubrication pump, or the first input shaftis rotated by an internal combustion engineby engaging a first engaging and disengaging unit to thereby drive the lubrication pump
