The present invention relates to a basketball stand lighting system comprising a fixing seat connected to a U-shaped supporting structure, a main stand, an inclined support frame, a telescopic frame outer pipe, a telescopic frame inner pipe, a lower fixing plate, a light, a lower support, and a column. This basketball stand lighting system allows convenient installation by using the basketball stand's own backboard height adjustment system to adjust the height of the installed lighting system, so there is no dangerous high altitude operation. The lighting system uses the basketball stand's own backboard height adjustment system to ensure that the installation is fixed in place. The lighting system saves time and labor, and the structure is ingenious and simple. This basketball stand lighting system need not employ complicated installation auxiliary equipment, and it has reduced time used when the equipment is loaded and unloaded.
