蕾丝花边（英语：lace）是一种以繁复的镂空花纹为特点的纺织品，以纱线相互打结、交错、撚绕，而形成具有空花的布料，主要用于衣物的装饰。有蕾丝风格的织品起源很古老，但真正的蕾丝花边知直到15世纪末才真正出现，刚开始是用来装饰教会祭坛，因此成为修道院中的手工艺而开始发展，经手的设计精致非凡，之后这样的技术流传至民间。在15世纪末至16世纪初的意大利大量生产了以装饰衣物为目的的蕾丝，不过在当时依然是圣职者、王公贵族等一部份特权阶级才能穿戴的奢侈品，在导入法国后成为主要产地，并受到细致设计极受欢迎的洛可可风格的影响下，无论是技术方面还是样式种类都进入了最盛期。 16世纪起在西欧广泛流行，并逐渐传遍世界。

Lace is a delicate fabric made of yarn or thread in an open weblike pattern, made by machine or by hand.

Originally linen, silk, gold, or silver threads were used. Now lace is often made with cotton thread, although linen and silk threads are still available. Manufactured lace may be made of synthetic fiber. A few modern artists make lace with a fine copper or silver wire instead of thread. On a totally different scale are the architectural lace fences by Dutch designers.
