The Trésor de la langue française informatisé or TLFi (French pronunciation: [tʁezɔʁ la lɑ̃ɡ(ə) fʁɑ̃sɛːz(ə) ɛ̃fɔʁmatize]; "Digitized Treasury of the French Language") is a digital version of the Trésor de la langue française or TLF ("Treasury of the French Language"), a 16-volume dictionary of the French language of the 19th and 20th centuries, which was published between 1971 and 1994. It is freely available via a web interface. It was previously sold as a CD-ROM for Mac and Windows.

Since 2008, there are applications for macOS, iOS and Android.

The TLFi was created by the Analyse et traitement informatique de la langue française (ATILF; Computer Processing and Analysis of the French Language) joint research group, a collaboration between the French National Center for Scientific Research and the University of Lorraine. French linguist Alain Rey participated in its creation.
