We generalize to the homotopy case a result of K. Mackenzie and P. Xu on relation between Lie bialgebroids and Poisson geometry. For a homotopy Poisson structure on a supermanifold M, we show that (TM, T^*M) has a canonical structure of an L∞-bialgebroid. (Higher Koszul brackets on forms introduced earlier by H. Khudaverdian and the author are part of one of its manifestations.) The underlying general construction is that of a "(quasi)triangular" L∞-bialgebroid, which is a specialization of a "(quasi)triangular" homotopy Poisson structure. We define both here.
