Using approximately 88 million B bar{B} pairs collected between 1999 and 2002, we place a 90% confidence level upper limit on the branching fraction of B(B^0 --> pi^0 pi^0) < 3.6 times 10^{-6}. This result is preliminary.14 pages, 5 postscript figues, submitted to ICHEP2002High Energy Physics - Experimenttext
