A laser projection apparatus includes a reflecting unit, a reflecting diffuser, a first lens array having a length and a width, a condensing lens having first and second lens portions and first and second center axes, a laser set emitting a first color light, an imaging module, and a projection lens. The reflecting unit reflects the first color light to the first lens portion. The reflecting diffuser reflects the first color light to travel along a light-exit axis of the second lens portion. The first lens array is disposed on the light-exit axis. The length along the first center axis and the width along the second center axis are less than or equal to one half of a diameter of the condensing lens and the diameter, respectively. The imaging module is disposed on the light-exit axis. The imaging module and the projection lens receive the first color light sequentially.
