AB Using a sample of (470.9 +/- 2.8) x 10(6) B (B) over bar pairs, we measure the decay branching fraction B(B-0 -> D*(-)pi(+)pi(-)pi(-)) = (7.26 +/- 0.11 +/- 0.31) x 10(-3), where the first uncertainty is statistical and the second is systematic. Our measurement will be helpful in studies of lepton universality by measuring B(B-0 -> D*(-)tau(+)nu(tau)) using tau(+) -> pi(+)pi(-)pi(+)(nu) over bar (tau) decays, normalized to B(B-0 -> D*(-)pi(+)pi(-)pi(-)).
