Provided is a cleaning tool for an optical connector wherein a cleaning chip (44) having a leading end surface (51) in which a delivery hole (53) and a winding hole (54) for a cleaning medium are bored and having an outer peripheral surface (52) is provided at a leading end. The leading end surface (51) has a first inclined surface (56) and a second inclined surface (57) which form the leading end of the chip (44) in a mountain shape in cross section, and a convex curved surface (58) which connects the first and second inclined surfaces and the outer peripheral surface (52). The first inclined surface (56) crosses the axis of the chip (44), and is inclined at an angle smaller than the inclination angle of a leading end surface of an APC connector. The second inclined surface (57) is formed such that an offset line (61) (ridgeline) at the tip of the chip (44) is located between the axis of the chip (44) and the winding hole (54), and is inclined at an angle greater than or equal to the inclination angle of the leading end surface of the APC connector. The convex curved surface (58) is inclined at an angle greater than or equal to the inclination angel of the leading end surface of the APC connector.　Consequently, it is possible to provide a cleaning tool for an optical connector, the cleaning tool being able to properly clean both a PC connector and an APC connector without using a rotation mechanism for rotating a chip.
