The Hong Kong Legal Information Institute (HKLII - pronounced 'H K Lee') is a free access legal information system developed and jointly operated by the University of Hong Kong Department of Computer Science and Faculty of Law, with the kind assistance of the Australasian Legal Information Institute (AustLII).

HKLII's mission is to provide free access to primary legal materials from Hong Kong (and some publicly available secondary materials) by use of technology that is both easy to use and powerful in the diversity of materials that it covers.

The system is based on data obtained from sources in Hong Kong and the region. Mark-up, processing, database structure, search engine facilities, and some other aspects of technical infrastructure are adapted from software provided by AustLII. The Hong Kong, China and Taiwan pages (and some subject pages) of the World Law index are jointly prepared by HKU Faculty of Law and AustLII. The day to day operation of HKLII is carried out by HKU Libraries. The overall facility is managed jointly by HKU Libraries and Faculty of Law.
