Wormhole solutions are obtained in the modified f(R, T) gravity with strange quark matter. The equation of state of the strange quark matter (SQM) is the phenomenological MIT Bag model. Both constant and density-dependent bag parameters (B) are considered in the framework of modified f(R, T) gravity. We have examined the possible construction of a stationary, spherically symmetric and spatially inhomogeneous wormhole spacetime supported by the SQM. It is shown that there are two types of wormhole solutions are permitted in the theory where null energy condition (NEC) is obeyed and in other case NEC is not satisfied with power law shape function. In the case of hybrid shape function, a new class of wormhole solutions are obtained satisfying all the energy conditions.
