Sydney Law School (informally Sydney Law or SLS) is the law school at the University of Sydney, Australia's oldest university. Sydney Law School began a full program of legal instruction in 1890 following the appointment of its first dean, having offered legal examinations since 1855.

The law school has produced many leaders in law and politics, including six prime ministers, four federal opposition leaders, two governors-generals, eleven federal attorneys-generals, and 20 out of 56 justices of the High Court—more than any other law school in Australia. The school has also produced 24 Rhodes Scholars and several Gates Scholars.

In 2010, the School replaced its graduate-entry Bachelor of Laws (LL.B.) degree with the Juris Doctor (J.D.) degree. The LL.B. degree remains as part of an undergraduate double degree program. Today, it has approximately 1,700 LL.B. and J.D. students, 1,500 postgraduate coursework students, and 100 postgraduate research students. There are now 24 chairs, including the Challis Professors of Law, Jurisprudence and International Law.
