We give a minireview of nonlocal field theory (infinite derivative field theory). We start with the discussion of the main peculiarities of nonlocal field theory on the example of d = 4 scalar *f*4 model. The nonlocal *f*4 model is ultraviolet finite, unitary and macrocausal. One of the problems of nonlocal field theory is that the form factor is an arbitrary entire function that makes the predictions extremely weak. We propose some additional principle that allows one to fix the form factor. Also, we review the main results obtained in nonlocal quantum gravity, namely that the nonlocal generalization of Einstein gravity leads to the superrenormalizable theory.
