瓦尔登湖（Walden; or, Life in the Woods)，又译湖滨散记，是美国作家亨利·戴维·梭罗所着的一本著名散文集。

该书出版于1854年，梭罗在书中详尽地描述了他在瓦尔登湖湖畔一片再生林中度过两年又两月的生活以及期间他的许多思考。瓦尔登湖地处美国马萨诸塞州东部的康科德镇，离梭罗家不远。梭罗把这次经历称为简朴隐居生活的一次尝试。

《瓦尔登湖》的中文译本有多种，例如有徐迟、张知遥、戴欢以及李继宏等翻译的版本。

Walden (/ˈwɔːldən/; first published as Walden; or, Life in the Woods), by noted transcendentalist Henry David Thoreau, is a reflection upon simple living in natural surroundings. The work is part personal declaration of independence, social experiment, voyage of spiritual discovery, satire, and (to some degree) manual for self-reliance. Thoreau also used this time to write his first book, A Week on the Concord and Merrimack Rivers.
