Abstract: A spherical binocular capable of being conveniently portable and suitable for use for watching a game in a baseball stadium, a soccer ground or the like. Two hemispherical shells are foldably or pivotally connected together into a spherical configuration. The hemispherical shells each are formed at a center thereof with an ocular through-hole, in which an ocular concave lens is fitted. A front plate is fitted in a front opening edge of each of the shells and formed at a center thereof with an objective opening, in which an objective convex lens is arranged so as to be aligned with the objective convex lens. When the hemispherical shells are folded over each other to align the front opening edges with each other, a holding pawl and holding groove of one of the hemispherical shells are fittedly engaged with a holding groove and a holding pawl of the other of the hemispherical shells, respectively.
