  We report the theoretical discovery of real-space multifold degenerate
Floquet-Bloch states in monolayer graphene coherently driven by twisted
circulalry-polarized light. Using Floquet theory, we characterize the
real-space structure of quasienergies and Floquet modes in terms of the orbital
angular momentum and radial vortex profile of light. We obtain the effective
real-space Floquet Hamiltonian and show it supports crossings of Floquet modes,
especially at high-symmetry $K$ and $\Gamma$ points of graphene, at specific
radial positions from the vortex center. At specific frequencies, the vortex
bound states form a multifold degenerate structure in real-space. This
structure is purely dynamically generated and controlled by the frequency and
intensity of twisted light. We discuss the experimental feasibility of
observing and employing the real-space multifold degeneracy for coherent
optoelectronic quantum state engineering.
