A fundus photographing apparatus (1) comprises: a photographing unit (3) including a fundus illumination optical system (10) to illuminate a fundus of a patients eye (E) and a fundus photographing optical system (30) having a light receiving element (35, 38) to obtain an image (F2) of the fundus of the patients eye illuminated by the illumination optical system and alignment means (6, 38, 80, 83) arranged to position the photographing unit with the patients eye based on a predetermined alignment reference position. The alignment means includes: extracting means (80) for extracting, by image processing, an image region (R1) formed by reflection light from a portion other than the fundus from the fundus image obtained by the fundus photographing optical system gravity center calculating means (80) for determining, by arithmetic processing, a gravity center position (O1) of the image region extracted by the extracting means and control means (80) for performing alignment control of the photographing unit with respect to the patients eye based on the gravity center position calculated by the gravity center calculating means and the alignment reference position.
