The utility model discloses a notebook computer chair. The notebook computer chair comprises a chair body with armrests, wherein a supporting plate (5) is arranged at the outer side of the armrest (1) at one side of the chair, and is connected with the armrest (1) through a connecting rod (2) which can rotate around a pin shaft (3); and the plate surface of the supporting plate (5) can rotate towards the inner front part of the chair and can be stably and horizontally suspended front above the chair surface. Because the supporting plate is arranged at the outer side of the armrest of the chair, thus when the supporting plate is used, the supporting plate only needs to be turned up to a horizontal position, namely the supporting plate is horizontally suspended and positioned front above the chair surface and used for placing a notebook computer or used as a general writing platform; and at ordinary times, the supporting plate can be retracted to the outer side of the armrest, so that the floor space of the chair is not increased, and the normal use of the chair cannot be obstructed. The notebook computer chair is simple in structure, and is very convenient to operate.
