We prove an \({\varepsilon}\)-regularity result for a wide class of parabolic systems $$u_t-\rm{div}\big(|\nabla u|^{p-2}\nabla u) = B(\cdot, u, \nabla u)$$with the right hand side B growing critically, like \({|\nabla u|^p}\). It is assumed a priori that the solution \({u(t,\cdot)}\) is uniformly small in the space of functions of bounded mean oscillation. The crucial tool is provided by a sharp nonlinear version of the Gagliardo–Nirenberg inequality which has been used earlier in the elliptic context by T. Rivière and the last named author.
