The present invention provides an elastically-buckled lamp, comprising a mounting base and a lamp body; there are more than three elastic buckles provided on the mounting base; arc-shaped grooves adapted to the elastic buckles are provided at an upper end of the lamp body, and the elastic buckles can be elastically deformed in a radial direction of the arc-shaped grooves and then inserted and clamped into the arc-shaped grooves; and when provided in the arc-shaped grooves, the elastic buckles are capable of sliding along the arc-shaped grooves to enable the lamp body to rotate relatively to the mounting base, so that it is easy to adjust mounting angles. Moreover, it is easy to mount and beautiful in appearance.
