LTM Limited (formerly LTIMindtree Limited) is an Indian multinational information technology services and consulting company based in Mumbai. A subsidiary of Larsen & Toubro, the company was incorporated in 1996 and employs more than 87,950 people.

The company was founded as L&T Information Technology Ltd in December 1996 as a subsidiary of Larsen & Toubro. During 2001–2002, the company's name was changed from L&T Information Technology Ltd. to L&T Infotech Ltd., and in the same year, the company achieved the assessed level of the Software Engineering Institute's (SEI) Maturity Level 5.

Between 2009 and 2012, parent Larsen & Toubro sought to scale up L&T Infotech by making a series of acquisition attempts, for Satyam Computer Services, Patni Computer Systems and Hexaware Technologies, all three of which proved to be unsuccessful.

In 2013–14, L&T Infotech's engineering services segment was acquired by parent Larsen & Toubro's newly created technology and engineering services subsidiary called L&T Technology Services.

In July 2016, L&T Infotech went public via an initial public offering (IPO) of ₹1,243 crore (US$184.98 million).

Between 2016 and 2017, L&T Infotech had contracts with the Income Tax Department and Central Board of Direct Taxes to detect income tax evasion using profiling, data models and social media analytics.

The company rebranded itself as 'LTI' with a tag line of 'Let's Solve' in May 2017.

In June 2019, Larsen & Toubro completed its hostile takeover of Bengaluru-based company Mindtree, despite opposition from the latter's promoters.
