Formerly, Lat Phrao was a
tambon of
Bang Kapi district, in what was then
Phra Nakhon province, before the unification of
Thonburi and
Phra Nakhon into the single administrative area of
Krung Thep (Bangkok). Later it was a sub-district (tambon) of the Bang Kapi District (amphoe), after naming conventions were changed for administrative districts of Bangkok. On 4 September 1989, Lat Phrao was split off from Bang Kapi along with
Bueng Kum as new districts. In 1997, the boundaries of Lat Phrao District were modified to balance the size and population of Bangkok's districts. The portion of Chorake Bua sub-district north of Khok Khram and Ta Reng canals was reassigned to
Bang Khen district, and portions of the Lat Phrao sub-district were added to
Wang Thonglang district. On 24 January 2002, portions of Wang Thonglang District were reassigned to Lat Phrao Sub-district. ==Administration==
