The Business Twenty (B20) is the official G20 dialogue with the business community. As the voice of the private sector to the G20, it represents the global business community across all G20 member states and all economic sectors. Formed in 2010, it is the first engagement group of the G20.

The B20 supports the G20 through specific policy recommendations, the consolidated representation of business interests and economic expertise. It also fosters dialogue between the public and private sector.
