Hi-Tech City (BHTC) is a business park in Kaliakair, Gazipur District, Bangladesh. Originally called Kaliakoir Hi-Tech Park, after the municipality in which it is located. Many companies are invested in this sector.

The hi-tech park was formally proposed in June 1999 at a meeting of the Board of Investment. A feasibility study was conducted in 2001 by the Bangladesh University of Engineering and Technology. A boundary wall was constructed in 2008. A further assessment was performed by PricewaterhouseCoopers in 2009. It said that one advantage of the location was that land acquisition was complete. In 2010, the Bangladesh Hi-Tech Park Authority (BHTPA) was formed to regulate and operate hi-tech business parks in the country.

By June 2015, the authority had awarded contracts for basic infrastructure. One of two parts of a bypass road for local residents was complete, as was an internal access road. Construction had begun on sewer lines and a sewage treatment plant; the boundary wall was being extended to enclose an expected expansion, and replaced where it had been demolished during other construction; installation of street lighting was underway; and refurbishment of a three-storey building built in 2009 but not yet occupied was in progress.

The original 232 acres (94 ha) site is divided into five blocks. Block 1 is reserved for government use. Blocks 2 and 5 are being built by Summit Technopolis, a joint venture between Summit Group of Bangladesh and Infinity Infotech Parks of India. Bangladesh TechnoSity is developing Block 3. As of 2020, Block 4 has not been awarded. Summit Technopolis broke ground on their portion on 28 February 2016. By June of that year, the project had been expanded to 355 acres (144 ha).

BHTC is the first ever Hi-Tech Park in Bangladesh, located at Kaliakoir upazilla in Gazipur district. It is well connected with all over the country through road, rail and air. It is situated only 40 km North from Dhaka city & 35 km away from Hajrat Shahjalal International Airport. The entire offside infrastructure development works have been completed by March 2017. The total Land Area of BHTC is 355 acres where 232 acres of land was divided into 5 blocks as per master plan. BHTPA has already appointed 2 developers for the development of BHTC as per PPP model and onsite infrastructure development is ongoing. The city having a world class business environment is considered as specialized zone to attract investor especially foreign investors where they could utilize vast potential of young, educated and technically skilled work force.
