Forstbotanischer Garten Tharandt, Botanical garden and arboretum in Tharandt, Germany.

The Forstbotanischer Garten Tharandt is a botanical garden and arboretum in Tharandt, Saxony, set on sloping ground with wide paths winding through trees and shrubs from many parts of the world. It holds one of Europe's largest collections of cold-hardy woody plants.

The garden was founded in 1811 by Heinrich Cotta as part of a forestry academy, making it one of the world's earliest scientific tree collections. This close link to forester training shaped the place from the very beginning.

The garden belongs to Dresden University of Technology and serves as a working place for forestry and botany students. Visitors often come across researchers or students taking samples and identifying plants among the trees.

The garden is open from March through October and is easy to explore on foot, with marked paths leading through the whole site. Guided tours for groups can be arranged on request.

The Zeisiggrundbrücke, a 117-metre bridge of wood and stainless steel completed in November 2003 for 645,000 euros, links the historic eastern garden with the North America section. It received the Saxon State Prize for Building Culture in 2006. The two halves are separated by the Zeisiggrund valley, through which the Dresden–Freiberg road runs.
