For $(X, \pi)$ a Poisson manifold, a submanifold $S \hookrightarrow X$ is called coisotropic if the restriction of the contraction map with the Poisson tensor
to the conormal bundle $N^* S \hookrightarrow T^* X|_S$ factors through the tangent bundle $T S$
Equivalently, $S\hookrightarrow X$ is coisotropic if the subalgebra of $C^\infty(X)$ of functions vanishing on $S$ is closed under the Poisson bracket.
A Poisson manifold induces a Poisson Lie algebroid, which is a symplectic Lie n-algebroid for $n = 1$. Its coisotropic submanifolds correspond to the Lagrangian dg-submanifolds (see there) of this Poisson Lie algebroid.
