Mo Mi (Thai: หมอมี, pronounced [mɔ̌ː mīː]) is a large intersection located in the centre of Bangkok's Chinatown quarter lies on the tripoint between Pom Prap of Pom Prap Sattru Phai district and Talat Noi with Samphanthawong of Samphanthawong district.

Mo Mi, formerly and still colloquially known as Sam Yaek (สามแยก, pronounced [sǎːm jɛ̂ːk]), which means "Three-Way Junction," and Sam Yaek Charoen Krung (สามแยกเจริญกรุง, pronounced [sǎːm jɛ̂ːk t͡ɕā.rɤ̄ːn krūŋ]), meaning "Three-Way Junction of Charoen Krung."

In 1898, a fire occurred in this area, spreading rapidly across the neighborhood because of its contemporary design of wooden framing with thatched roofs combined with the high density of houses.

[3] The area around Mo Mi in the past was well-known as a centre of chick and duckling stores, but at present there is only one left on Rama IV road.

[6] The vacant land from the demolition has been developed into Chinatown Market Chaloem Buri (named after its counterpart intersection on Yaowarat side), a new night market, along with the installation of a Chinese archway called "Vajirathamrong 72 Phansa" to celebrate the 72nd birthday of King Vajiralongkorn (Rama X), alongside a similar Chinese archway at the foot of Damrong Sathit bridge.
