We present a Dalitz-plot analysis of charmless B{sup {+-}} decays to the final state {pi}{sup {+-}}{pi}{sup {+-}}{pi}{sup {+-}} using 210 fb{sup -1} of data recorded by the BABAR experiment at {radical}(s)=10.58 GeV. We measure the branching fractions B(B{sup {+-}}{yields}{pi}{sup {+-}}{pi}{sup {+-}}{pi}{sup {+-}})=(16.2{+-}1.2{+-}0.9)x10{sup -6} and B(B{sup {+-}}{yields}{rho}{sup 0}(770){pi}{sup {+-}})=(8.8{+-}1.0{+-}0.6{sub -0.7}{sup +0.1})x10{sup -6}.= Measurements of branching fractions for the quasi-two-body decays B{sup {+-}}{yields}{rho}{sup 0}(1450){pi}{sup {+-}}, B{sup {+-}}{yields}f{sub 0}(980){pi}{sup {+-}} and B{sup {+-}}{yields}f{sub 2}(1270){pi}{sup {+-}} are also presented. We observe no charge asymmetries for the above modes, and there is no evidence for the decays B{sup {+-}}{yields}{chi}{sub c0}{pi}{sup {+-}}, B{sup {+-}}{yields}f{sub 0}(1370){pi}{sup {+-}} and B{sup {+-}}{yields}{sigma}{pi}{sup {+-}}.
