An optical fiber connector for positioning a number of optical fibers is provided. The optical fiber connector includes an assembling portion and a number of guiding blocks protruding from the assembling portion. The assembling portion defines a number of positioning holes corresponding to the optical fibers in position. The guiding blocks and the positioning holes are alternatively arranged on the assembling portion. Each guiding block includes a wedge portion at an end away from the assembling portion for guiding a corresponding one of the optical fibers into a corresponding one of the positioning holes.
