Lam Sali (Thai: ลำสาลี, pronounced [lām sǎːlīː]) is a four-way intersection in Hua Mak subdistrict, Bang Kapi district, Bangkok.

Since in the olden days, this area was a countryside that was full of waterways, such as Khlong Saen Saep canal and rice fields with grove woods, known as "Thung Bang Kapi" (ทุ่งบางกะปิ; Bang Kapi Field), and was a Muslim settlement.

There was an old man named "To Kili" (โต๊ะกีลี) or "Ta Samli" (ตาสำลี) whose job was to raise buffalos for the locals.

He often drove a herd of buffalo to eat grass at front of the Yamee-Unmuttageen Mosque in present day.

[1] The Lam Sali intersection had extreme traffic jams beginning December 7, 2018, when the Lam Sali overpass (only inbound side) was closed for one year due to the construction of the MRT Orange Line.
