The following is a list of [[indefinite integral]]s ([[antiderivative]]s) of expressions involving the [[inverse hyperbolic function]]s. For a complete list of integral formulas, see [[lists of integrals]].

* In all formulas the constant ''a'' is assumed to be nonzero, and ''C'' denotes the [[constant of integration]].
* For each inverse hyperbolic integration formula below there is a corresponding formula in the [[list of integrals of inverse trigonometric functions]].
