Ujiji is the oldest town in western Tanzania. It is about 10 km south of Kigoma . Ujiji was a "slave trade" town settled by Arab peoples.

Ujiji is the place where Burton and Speke first reached the shore of Lake Tanganyika in 1858 and where Dr. Livingstone met Stanley in 1871. A monument known as the "Dr. Livingstone Memorial" was constructed to commemorate the meeting. There is a former slave route near the market.
