We introduce and study a generalization of Schur's P-/Q-functions associated with a polynomial sequence, which can be viewed as ``Macdonald's ninth variation'' for P-/Q-functions. This variation includes as special cases Schur's P-/Q-functions, Ivanov's factorial P-/Q-functions and the t=-1 specialization of Hall-Littlewood functions associated with the classical root systems. We establish several identities and properties such as generalizations of Schur's original definition of Schur's Q-functions, a Cauchy-type identity, a generalization of the Józefiak-Pragacz-Nimmo formula for skew Q-functions, and a Pieri-type rule for multiplication.
