Abstract: We have searched for the charmless hadronic decay of ${B}^{0}$ mesons into two neutral pions. Using 9.13 ${\mathrm{fb}}^{\mathrm{\ensuremath{-}}1}$ taken at the $\ensuremath{\Upsilon}(4S)$ with the CLEO detector, we obtain an improved upper limit for the branching fraction $\mathcal{B}{(B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0})<5.7\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}$ at the 90% confidence level.
