The present invention provides a cell evaluation device, a cell evaluation method and a cell evaluation program capable of evaluating, when evaluating a predetermined evaluation target-cell using evaluation results of peripheral cells thereof, the evaluation target-cell with high accuracy. The cell evaluation device includes an image acquisition unit 30 that acquires a cell-image obtained by imaging a cell-group; a cell evaluation unit 32 that specifies an evaluation target-cell and peripheral cells around the evaluation target-cell in the cell-group, and evaluates the evaluation target-cell based on evaluation results of the peripheral cells; and a boundary setting unit 31 that sets a boundary in the cell-image based on a state of the cell-group, in which when specifying the peripheral cells, the cell evaluation unit 32 specifies only cells that are present in a divided region where the evaluation target-cell is present among plural divided regions divided by the boundary, as the peripheral cells.
