In this paper, it is shown that the only (nontrivial) finitely generated rotation invariant ideals in H°° are znH°° for some positive integer n. Using results about function algebras, it is shown that other rotation invariant ideals exist. Rotation invariant ideals of other subalgebras of L°° are also studied.
