The Bangladesh Investment Development Authority (BIDA) (Bengali: বাংলাদেশ বিনিয়োগ উন্নয়ন কর্তৃপক্ষ) is the apex investment promotion agency (IPA) of Bangladesh under the Chief Adviser's Office.

BIDA promotes and facilitates private investment and advocates business-friendly policies.

BIDA also provides regulatory services including registration, approvals and recommendations.

BIDA was formed on 1 September 2016[1] through the Bangladesh Investment Development Authority Act [2] that merged the erstwhile Board of Investment and Privatization Commission.

BIDA established this platform by driving the digitization and integration of the investor services of various ministries, departments and agencies in Bangladesh.
