We study hyper dual numbers and hyper dual number matrices. Firstly, we give some basic properties of dual numbers and hyper dual numbers. Next, we investigate hyper dual number matrices using the properties of dual number matrices. Then we define the dual adjoint matrix of hyper dual matrices and describe some of their properties.
