The Energy eigenstates of a quantum system are the set of eigenvalues and eigenvectors obtained by solving the time-independent Schrödinger equation for the system in question,

\hat{H}\Psi_n=E_n\Psi_n

where \hat{H} is the time-independent Hamiltonian operator,

\Psi is the nth energy eigenvector (also known as eigenfunction or wavefunction),

and E_n is the nth energy eigenvalue.

In the case of a system with a time-independent Hamiltonian operator, this set of eigenvalues are also called stationary states, because they are time-independent.
