太魯閣國家公園是台灣的第四座國家公園，1986年11月12日公告計畫，1986年11月28日成立管理處。位於台灣東部，地跨花蓮縣、台中縣、南投縣三個行政區。園內有台灣第一條東西橫貫公路通過，稱為中橫公路系統。

太魯閣國家公園的特色為峽谷和斷崖，崖壁峭立，景緻清幽，「魯閣幽峽」因而名列台灣八景之一。另外，園內的高山地帶保留了許多冰河時期的孑遺生物，如山椒魚等。

Taroko National Park is one of the seven national parks in Taiwan and was named after the Taroko Gorge, the landmark gorge of the park. It spans the counties of Hualien, Taichung, and Nantou on the island of Taiwan.

Taroko Gorge and its surrounding area are well known for their abundant supply of marble, leading to its nickname, "The Marble Gorge". The rock now seen in Taroko began over 200 million years ago as sediment on the bottom of the ocean. As the sediment collected, it was subject to increasingly large amounts of pressure which eventually hardened it into limestone. Over the past 100 million years, tectonic compression between the Philippine Sea Plate and the Eurasian Plate supplied additional pressure that metamorphosed the limestone into marble. Uplifting forces from the plate collision pushed this rock above the surface of the ocean to where we see it today. In fact, the region is still being uplifted by approximately 0.5cm per year.

The gorge itself was carved into the marble by the erosive power of the Liwu River.

In addition, there are known to be jade in this gorge. This jade is only found in Taiwan and the jade from this area supplies the jade market in Hualien. These mountains can be seen from rafting (a common activity during summer months in Taroko Gorge) through the rivers.
