We present wide‐field, high‐resolution imaging observations in  12 CO 3 → 2 and H 2  1–0 S(1) towards a ∼1 deg 2  region of NGC 2264. We identify 46 H 2  emission objects, of which 35 are new discoveries. We characterize several cores as protostellar, reducing the previously observed ratio of pre‐stellar/protostellar cores in the NGC 2264 clusters. The length of H 2  jets increases the previously reported spatial extent of the clusters. In each cluster, &lt;0.5 per cent of cloud material has been perturbed by outflow activity. A principal component analysis of the  12 CO data suggests that turbulence is driven on scales &gt;2.6 pc, which is larger than the extent of the outflows. We obtain an exponent α= 0.74 for the size–linewidth relation, possibly due to the high surface density of NGC 2264. In this very active, mixed‐mass star‐forming region, our observations suggest that protostellar outflow activity is not injecting energy and momentum on a large enough scale to be the dominant source of turbulence.
