Presumably you refer to the 11" iPad Pro? If so - yes - but some explanation and clarification is required...
With the sole exception of the new (just released) 11" iPad Pro M2, all prior models of the iPad Pro 11" (i.e., the first through fourth generation iPad Pro 11") have identical physical dimensions. However, the first generation iPad Pro 11" does not have the larger rear camera array "bump" found on the second, third and fourth generation iPad Pro 11".
As such, due to the camera bump, a fitted case designed for the first generation iPad Pro 11" will not fit any later model iPad Pro 11". By contrast, cases designed for the second, third and fourth generation iPad Pro 11" have a larger rear aperture to accommodate the larger camera array - and are therefore compatible with all models of iPad Pro 11" other than the new 11" iPad Pro M2.
Hopefully this explanation will assist with determining compatibility of the proposed case with your iPad.
