长岛冰茶（英语：Long Island Iced Tea）虽取名冰茶，却是在没有使用红茶的情况下，调制出具有红茶色泽与口味的鸡尾酒。调制的主要成份为伏特加、琴酒、兰姆酒与龙舌兰酒，属于烈酒，酒精浓度超过40%。

起源之一的说法为1920年代美国禁酒令期间，酒保将烈酒与可乐混成一杯看似茶的饮品，来钻法令漏洞；起源之二是据说在1972年，由长岛橡树滩客栈（Oak Beach Inn）的酒保发明了这种以四种基酒混制出来的饮料。

A Long Island Iced Tea is a type of alcoholic mixed drink typically made with tequila, vodka, light rum, triple sec, gin, and a splash of cola, which gives the drink the same amber hue as its namesake. It is so named because of the resemblance to the color and taste of iced tea. A popular version mixes equal parts vodka, gin, tequila, rum, and triple sec with 1½ parts sour mix and a splash of cola.
