韦伯伦商品（Veblen Good），又称炫耀财，是经济学上用以描述一种商品，其特色是商品需求与商品价格成正向关系，而非正常需求法则的反向关系。这种商品能满足人类的虚荣心，是财富与地位的炫耀，故称为炫耀性消费（Conspicuous consumption）。此名词源于其概念提出者托斯丹·范伯伦（Thorstein Veblen）。

价格高昂的宝石、名车、名牌精品等奢侈品皆为韦伯伦商品的例子。炫耀财同时也是正常财。

根据张五常教授分析，炫耀财没有违反需求定律。张教授认为人们消费炫耀财，也是购买‘炫耀’(炫耀也是经济物品)。假如有一手表价值50000元，有10单位炫耀(一单位炫耀价值5000元)，同时，另一手表价值70000元，有50单位炫耀(一单位炫耀价值1400元)，按照需求定律，我们就能解释为何韦伯伦商品价愈高，交易量更高。一些购买能力高而且只考量炫耀的人会因一单位炫耀价值下降，倾向售买70000元手表而非50000元手表。

In economics, Veblen goods are types of material commodities for which the demand is proportional to its high price, which is an apparent contradiction of the law of demand; Veblen goods also are commodities that function as positional goods. Veblen goods are types of luxury goods, such as expensive wines, jewelry, fashion-designer handbags, and luxury cars, which are in demand because of the high prices asked for them. The high price makes the goods desirable as symbols of the buyer's high social status, by way of conspicuous consumption and conspicuous leisure; conversely, a decrease of the prices of Veblen goods would decrease demand for the products.
