An iris detection device includes a candidate detection unit, a candidate narrowing-down unit, and an iris specifying unit. The candidate detection unit detects circular regions as iris candidates from images captured by an infrared camera. The candidate narrowing-down unit narrows down the detected iris candidates into a predetermined number of iris candidates with use of data items of images of surroundings of each of the iris candidates. The iris specifying unit specifies one of the predetermined number of iris candidates obtained by the narrowing-down as an iris by matching between gradients of a contour of each of the predetermined number of iris candidates and iris templates.
