In grammar, a content clause is a dependent clause that provides content implied or commented upon by an independent clause. The term was coined by Danish linguist Otto Jespersen. They are also known as noun clauses.

In English, there are two main kinds of content clauses: declarative content clauses (or that-clauses), which correspond to declarative sentences, and interrogative content clauses, which correspond to interrogative sentences.
