A bicycle chain comprises a first outer link plate and a second outer link plate. A first outer-link longitudinal axis extends through a first outer-link center axis and a second outer-link center axis to divide a first outer surface into a first side and a second side when viewed in an axial direction. A second outer-link longitudinal axis extends through a third outer-link center axis and a fourth outer-link center axis to divide a second outer surface into a third side and a fourth side when viewed in the axial direction. The fourth side includes a first circumferential area and a first chamfer free area. The first circumferential area has a first angle equal to or larger than 20 degrees. The first chamfer free area is adjacent to the first circumferential area. At least one second chamfer is provided outside the first chamfer free area.
