红利，英文为bonus或extra dividend，是公司（或其它按出资资本决定收益分配的非公司经济组织，如中国大陆的农村信用合作社）的税后利润提取各种公积金、公益金、优先股股息后剩余的盈利，按照股东（不含优先股股东）持股比例分配给股东。股东获得红利的多少根据公司的经营盈亏而变动，是不固定的。而股息是按照股票票面金额的一个固定比率向股东支付利息，不随股票二级市场上股价波动与公司经营业绩情况而变化。

A bonus share is a free share of stock given to current shareholders in a company, based upon the number of shares that the shareholder already owns While the issue of bonus shares increases the total number of shares issued and owned, it does not change the value of the company. Although the total number of issued shares increases, the ratio of number of shares held by each shareholder remains constant.
