吊带，又称背带，是穿在双肩上用来吊起裤子的两条带子。带子通常是带有弹性的，或者整条都有弹性，或者仅在带子和裤子相接触的部分带有弹性。大多数吊带是用织布制作，在背后交叉成X和Y型。

Suspenders (American English, Canadian English) or braces (British English) are fabric or leather straps worn over the shoulders to hold up trousers. The straps may be elasticated, either entirely or only at attachment ends, and most straps are of woven cloth forming an X or Y shape at the back. Suspenders are typically attached to trousers with clips or buttons using leather tabs at the ends. Outside the United States the term suspenders, or suspender belt, refers to a garment used to hold up stockings. This is called a garter belt in American English.
