仿真干酪是指烹饪上的干酪替代物，以取代菜式上因客人需求或避免过敏发作的干酪。无论是融点或价格，仿真干酪均与干酪不同，但其较低廉的售价诱使商界多用，以减轻经营成本。

仿真干酪大多由大豆制成，但也有由稻米、杏仁、营养酵母或其它非乳品物质制成。仿真干酪就像植物性奶油替代品，用于各种起司产品。这些产品通常被某种食物偏好者消费，例如纯素食主义、教条限制(大部份的仿真干酪均由拉比认可，是符合教规的食物)、乳糖不耐症或牛奶过敏。

以下为一些比较常见的素食仿真干酪品牌，均不含酪蛋白：Cheed, Cheezly, FYH Vegan Gourmet Cheese, NuttyCow NutCheese, Sheese, Teese,及Tofutti。此外尚有一些不含大豆成份的全素仿真干酪，包括有：Daiya, Dr.Cow, Chreese及Veganrella，全部均为己认证的全素食品，所以100%保证不含酪蛋白。

Cheese analogues (more widely known as cheese alternatives) are products used as culinary replacements for cheese. These include vegan cheeses as well as some dairy products, such as processed cheese or Kraft Singles, that do not qualify as true cheeses. These foods may be intended as replacements for cheese, as with vegan products, or as imitations, as in the case of products used for salad bars and pizza-making, which are generally intended to be mistaken for real cheese, but have properties such as different melting points or lower costs that make them attractive to businesses.
