We present measurements of the branching fraction and time-dependent CP asymmetries
in B0 -> JPsi pi0 decays based on (231.8 +/- 2.6) x 10**6  asymmetries Y(4S) -> BBbar
decays collected with the BaBar detector at the SLAC PEP-II asymmetric-energy B factory. 
We obtain a branching fraction
       B(B0 -> JPsi pi0) = (1.94 +/- 0.22 (stat.) +/- 0.17 (syst.)) x 10**-5.

We also measure the CP asymmetry parameters 
       C = -0.21 +/- 0.26 (stat.) +/- 0.06 (syst.)
   and S = -0.68 +/- 0.30 (stat.) +/- 0.04 (syst.).
