The Group of 15 (G-15) was established at the Ninth Non-Aligned Movement Summit Meeting in Belgrade, Yugoslavia in September 1989.

This informal forum was set up to foster cooperation and provide input for other international groups, such as the World Trade Organization and the Group of Eight. It is composed of countries from North America, South America, Africa, and Asia with a common goal of enhanced growth and prosperity. The G15 focuses on cooperation among developing countries in the areas of investment, trade, and technology. The membership of the G15 has expanded to 17 countries, but the name has remained unchanged. Chile, Iran and Kenya have joined since the start and Yugoslavia is no longer part of the group. Recently, former member-state Peru decided to leave the group of 15.

Other organs and functions of the G-15 include:

Year 15 (XV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Caesar and Flaccus (or, less frequently, year 768 Ab urbe condita). The denomination 15 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
