  Perturbative renormalization provides the bedrock of understanding quantum
field theories. In this work, I point out an alternative way of renormalizing
quantum field theories, which is naturally encountered and well known for the
case of large N scalar field theories. In terms of bare parameters, this
non-perturbative alternative renormalization differs qualitatively from its
perturbative cousin: in the continuum limit, the bare coupling constant goes to
zero instead of infinity, and there is no wave-function counterterm. Despite
these differences, the resulting n-point functions of the theory are finite. I
provide explicit results for alternative renormalization for the O(N) model and
QCD with $N_f=12$ flavors in 3+1 dimensions.
