Lam Luk Ka (Thai: ลำลูกกา, pronounced [lām lûːk kāː]) is a district (amphoe) of Pathum Thani province, part of Bangkok Metropolitan Region.

Originally, Lam Luk Ka was a vast grassland interspersed with scrubland and wetlands, as well as a habitat for various kinds of wildlife called "Thung Luang" (ทุ่งหลวง, "great field"). For the development of the country, King Chulalongkorn (Rama V) ordered the Khlong Rangsit to be cut through this area. The effect of having a canal for irrigation flowing through, as a result, more people migrated to live here.

The district had waterways flowing through it, confluence into the pond shaped like a crow's feet. Therefore attracting many species of birds to nest here because of the fertile pond. Locals therefore called "Bueng Lam Luk Ka", literally translated as "course of baby crow" or "ballard of baby crow" in another sense, included there are many crow sculptures adorn buildings and lampposts along the secondary highway through the city.

When the government formed the amphoe Lam Luk Ka in 1904, they cut the prefix "Bueng" (pond) off.^[1]
