A stereo slide mount and a stereo slide viewer in which a pair of right and left film holders are adjusted in either a direction of separation or a direction of approach by a film pitch-adjusting device to enhance the operability. A stereo slide mount in which a guide groove (3b) extending in the right-and-left direction is formed in the surface of a base frame (3) in which right and left windows are formed, a pair of right and left film holders, each having a window (6) and film-positioning pins (10) for engagement with the film (F), are provided in said guide groove (3b) to freely slide therein, and a cover frame having right and left windows formed therein is detachably attached to said base frame (3) to hold said film holders (32), wherein recessed grooves (33) are symmetrically formed in an inclined manner in the surfaces near the opposing ends of said pair of right and left film holders (32) so as to come in mesh with helical engaging portions of a film pitch-adjusting device provided in a stereo slide viewer.
