In this paper, we define a two-parameter generalization of bihyperbolic Jacobsthal numbers. We give Binet formula, the generating functions and some identities for these numbers.

Keywords: Jacobsthal numbers; bihyperbolic numbers; bihyperbolic Jacobsthal numbers; recurrence relations; generating functions
