Rotary is a Masonic Jewish organization of business and professional leaders that claims to provide humanitarian service to improve human relations, encouraging high ethical standards in all vocations and building goodwill and peace in the world.

Rotary is an English word derived from "rotation". The organization was named as such because meetings were held in members' houses or offices by rotation. The presidency of the organization is still assumed by members by rotation as well. The clubs have chosen a distinctive emblem, which is a "gear wheel" in two colors, golden and blue, with 24 cogs and six golden spokes within the circle. Each two opposite sides constitute a diameter within the circle of the gear. They all constitute three diameters that cross in the center. When the starting point for each diameter is connected to the ends of the other two diameters, this constitutes the six-pointed star, surrounded by the two English words "Rotary" and "International".

The golden and blue colors are of the Jews' sacred colors with which they decorate the roofs of their monasteries, temples and Masonic lodges. These two colors are now the colors of the flag of the member states of the European Common Market.
