A table lamp including a base, a lamp handle, a lamp holder provided with a light source and an adjustment component. The base can be placed on a placement surface, and a bottom surface of the base is a curved surface. The adjustment component can adjust the center of gravity of the table lamp by varying the center of gravity thereof, to thereby change a contact position of the bottom surface of the base and the placement surface, and thus change the illumination angle of the lamp holder. Since this technical solution adjusts the illumination angle of the lamp holder by adjusting the center of gravity of the table lamp instead of rotating the lamp holder, it solves the problem of breakage of the connection part of the lamp handle and the lamp holder caused by rotation of the lamp holder.
