According to one embodiment, an X-ray diagnostic apparatus includes at least a tabletop support, an arm, a position storing unit, and a mechanism controlling unit. The tabletop support supports a tabletop movably in a longitudinal direction, a raising/reclining direction, and an upper/lower direction of the tabletop. The arm holds an X-ray tube and an X-ray detector movably in an approaching/separating direction with respect to the tabletop support. The position storing unit stores a photographing position of the arm and a photographing position of the tabletop in association with each other. When the arm is at a retraction position, the mechanism controlling unit moves the tabletop in the raising/reclining direction and the upper/lower direction to maintain a position in at least the upper/lower direction of a region of the object corresponding to a photographing position of the arm stored by the position storing unit.
