I first introduce the Connes-Kreimer approach to renormalisation in commutative field-theory. Recently, some noncommutative scalar models were proven also to be renormalisable. Despite the non-local character of these models, I shall present in the second part of my talk the generalisation of this Connes-Kreimer approach to noncommutative renormalisation.
