The fisheye lens comprises lens elements constituting a first group, lens elements and an iris constituting a second group, and lens elements constituting a third group, arranged from an object side toward an image side. The first group is constituted by two to three lens elements, wherein all of the lens elements of the first group have negative refractive powers. The first lens element which is nearest to the object side, from among the lens elements of the first group, is a negative Meniscus lens element the convex plane of which is directed toward the object side, and the other lens elements have refractive indexes higher than 1.7 and Abbe numbers of 40 or higher. The second group is constituted by two to four lens elements, and the lens elements nearest and second nearest to the object side, from among the lens elements of the second group, form a cemented doublet. The lens element which is nearest to the object side, from among the lens elements of the second group, has a positive refractive power, a refractive index higher than 1.7, and an Abbe number of 30 or lower.
