In this paper, we consider the usual Lucas numbers and the generalized order-k Fibonacci numbers. Then we give a new definition for generalization of the Lucas numbers. Therefore, we give the generalized order-k Fibonacci and Lucas functions. Further, we derive new relationships between these functions.
