Pho Sam Ton (Thai: โพธิ์สามต้น, pronounced [pʰōː sǎːm tôn]) is a three-way junction between the Itsaraphap and Wang Doem Roads in the area of Wat Tha Phra and Wat Arun subdistricts in the Bangkok Yai district.

Pho Sam Ton was the site for the Burmese camp controlled by commanders Suki and Mongya.

The Burmese army used the camp as a base to forcibly move the Siamese to Ava (now Inwa).

Pho Sam Ton is often considered as the first junction along the Itsaraphap Road from Ban Khaek.

In the 1990s, the intersection between Pho Sam Ton to Ban Khaek was home to a number of pubs, and was popular with young people and students.
