股东大会由全体股东组成，是公司的最高权力机构。分为年度股东大会和临时股东大会。年度股东大会每年召开一次，应当于上一会计年度结束后的6个月内举行。临时股东大会则会在特殊情形时在法律规定期限内召开。股东会的议案投票通过与否并非取决于投票股东人数，而是由投票股东的持股比例加起来是否超过全部股权的半数来决定。在某些国家如美国，部份股东如创业时的股东，可以在股东大会获得比他们的持股比例更高的投票权，例如持有一股股票却拥有两股股票的投票权。一般而言，股东会皆由公司的负责人（如董事长）亲自主持。

An annual general meeting (commonly abbreviated as AGM, also known as the annual meeting) is a meeting of the general membership of an organization.

These organizations include membership associations and companies with shareholders.

These meetings may be required by law or by the constitution, charter, or by-laws governing the body. The meetings are held to conduct business on behalf of the organization or company.
