  Electromagnetic wave lensing, a common physical phenomenon recognized in
visible light for centuries, finds extensive applications in manipulating light
in optical systems such as telescopes and cameras. Magnetohydrodynamic wave is
a common perturbation phenomenon in the corona. By using high spatio-temporal
resolution observations from the Solar Dynamics Observatory, here, we report
the observation of a magnetohydrodynamic wave lensing in the highly ionized and
magnetized coronal plasma, where quasi-periodic wavefronts emanated from a
flare converged at a specific point after traversing a coronal hole. The entire
process resembles an electromagnetic wave lensing from the source to the focus.
Meanwhile, the magnetohydrodynamic wave lensing is well reproduced through a
magnetohydrodynamic numerical simulation with full spatio-temporal resolution.
We further investigate potential applications for coronal seismology, as the
lensing process encodes information on the Alfv\'en speed, in conjunction with
favorable geometric and density variations.
