黄金森林罗斯洛立安 （英语：Lothlórien），中土大陆的地名，意思是「盛开花朵的梦土」，居住着诺多族、辛达族和南多精灵。凯兰崔尔和凯勒鹏是罗斯洛立安的统治者。唯一美丽程度可与罗斯洛立安媲美的只有维拉罗瑞安的罗瑞安花园。

罗斯洛立安的辛达语古称是罗瑞林多瑞安 Laurelindórinan，「歌唱的黄金谷」 Land of the Valley of Singing Gold；又称Lórinand，「黄金之谷」 Golden Valley；亦称罗瑞安 Lórien。洛汗语中称为Dwimordene 「幽灵森林」，西方语称黄金森林 The Golden Wood。

In J. R. R. Tolkien's legendarium, Lothlórien or Lórien is the fairest realm of the Elves remaining in Middle-earth during the Third Age.

The realm plays an important part in The Lord of the Rings as the Elven centre of resistance against Sauron and is a symbol for the Elves' aesthetics of preservation which provides a space 'out of time' for the characters who both live and visit there. With Lothlórien, Tolkien reconciles otherwise conflicting ideas regarding time-distortion in Elfland from various traditional sources such as Thomas the Rhymer (13th/14th century) and the Danish folk-play Elverhøj (1828).
