We present a study of exclusive neutral pion production in neutrino-nucleusNeutral Current interactions using data from the NOMAD experiment at the CERNSPS. The data correspond to $1.44 \times 10^6$ muon-neutrino Charged Currentinteractions in the energy range $2.5 \leq E_{\nu} \leq 300$ GeV. Neutrinoevents with only one visible $\pi^0$ in the final state are expected to resultfrom two Neutral Current processes: coherent $\pi^0$ production, {\boldmath$\nu + {\cal A} \to \nu + {\cal A} + \pi^0$} and single $\pi^0$ production inneutrino-nucleon scattering. The signature of coherent $\pi^0$ production is anemergent $\pi^0$ almost collinear with the incident neutrino while $\pi^0$'sproduced in neutrino-nucleon deep inelastic scattering have larger transversemomenta. In this analysis all relevant backgrounds to the coherent $\pi^0$production signal are measured using data themselves. Having determined thebackgrounds, and using the Rein-Sehgal model for the coherent $\pi^0$production to compute the detection efficiency, we obtain {\boldmath $4630 \pm522 (stat) \pm 426 (syst)$} corrected coherent-$\pi^0$ events with $E_{\pi^0}\geq 0.5$ GeV. We measure {\boldmath $\sigma (\nu {\cal A} \to \nu {\cal A}\pi^0) = [ 72.6 \pm 8.1(stat) \pm 6.9(syst) ] \times 10^{-40} cm^2/nucleus$}.This is the most precise measurement of the coherent $\pi^0$ production todate.
