优先座（英语：Priority seats），亦称「博爱座」，其概念主要是来自北欧地区无障碍环境当中的一部份，希望残障者都能像一般人正常的上下公车。优先座的为孕妇、病者、负伤者、老人和残障人士所设的优先座位，坐在优先座上的人必须礼让上述的4种人士，但并没有硬性规定，完全是发自内心。交通运输机构时常呼吁乘客要让座给有需要人士。在一些国家，残障人士只要出示证件，就能无条件搭乘博爱座（没有也可以，只要可证明自己真的是残障人士）。博爱座在当今的公车、地铁、捷运以及部份设有座椅的公共场所等，都可以看到。常见下列标示：「请让座给老弱妇孺」、「请让座给有需要的人」等等。

Priority seats have been designated in public transport vehicles by certain transport operators to allow elderly, disabled, pregnant women and the injured to ride public transport with an equal degree of access and comfort as normal people. Priority seats can be found on various public transportation, including the mass transit railways, buses, minibuses, and trams. The slogan "Please offer your seat to anyone in need" is often displayed beside the seat. The elderly, disabled, pregnant, and injured have priority to take these seats. In most cases, there is no regulation to restrict the use of priority seats, but people are expected to offer their seats to those in need.
