In the present investigation, our main aim is to derive some conditions on starlikeness, convexity, and close-to-convexity of  normalized hyper-Bessel functions. Also we give some similar results for classical Bessel functions by using the relationships between hyper-Bessel and Bessel functions. As a result of the obtained conditions, some examples are also given.
