「丛林流浪」（Waltzing Matilda）是澳大利亚最具代表性的传统民谣（乡村歌曲或民歌）。由于几乎每个澳大利亚人都会哼唱，所以被称为是「澳洲的非官方国歌」。

歌名中的「Matilda」是澳洲俗语『旅行袋』的意思。这种旅行袋是旅人们徒步旅行时，用来背着家当的大布袋。

「丛林流浪」歌词内容是描述一个四处漂泊的工人（或流浪者），在丛林泡了杯茶、捕了只羊吃时，羊原本的主人带了三位警员来逮捕他（当时犯了偷窃罪的人会被判处吊刑），这个流浪者闻知便逃逸，最后无处可躲藏，于是跃入湖中，在自我了结生命前，犹对着前来拘捕他的人高喊『你们永远活捉不了我的』的小故事。

"Waltzing Matilda" is Australia's best-known bush ballad, and has been described as the country's "unofficial national anthem".

The title was Australian slang for travelling on foot (waltzing, derived from the German auf der Walz) with one's belongings in a "matilda" (swag) slung over one's back. The song narrates the story of an itinerant worker, or "swagman", making a drink of billy tea at a bush camp and capturing a jumbuck (sheep) to eat. When the sheep's owner, a squatter, arrives with three police officers to arrest the swagman for the theft, he commits suicide by drowning himself in a nearby billabong (watering hole), after which his ghost haunts the site.
