A projection apparatus includes a projection unit configured to project an image, an operation receiving unit configured to receive an operation, and a control unit configured to control the projection unit. The control unit controls the projection unit to project a first adjustment image for selecting a position to be subjected to an adjustment of the image to be projected by the projection unit. When the operation receiving unit receives an operation for determining the adjustment target position while the projection unit is projecting the first adjustment image, the control unit controls the projection unit to project a second adjustment image different from the first adjustment image in an area corresponding to the adjustment target position identified by the determination operation received by the operation receiving unit.
