  Suppose that $G$ is a topological group and $ C $ a compact subset of $G$. In
this paper we define group nonexpansive mappings and then we consider $\sc =
\{T_{i} : i \in I \}$ as a family of the group nonexpansive mappings on $C$.
Also we study the existence of group nonexpansive retractions $P_{i}$ from $C$
onto $\text{Fix}(\sc)$ such that $P_{i}T_{i} = T_{i}P_{i} = P_{i}$.
