The Fulfillment Amphitheater (Chinese: 圓滿戶外劇場; pinyin: Yuánmǎn Hùwài Jùchǎng) is a large-scale outdoor amphitheater in Wen-Hsin Forest Park on Wenxin Road, Nantun District, Taichung, Taiwan.

The built-in Amphitheater stage is an open performance space ranging between 40 and 51 meters wide.

Since August 5, 2006, a wide variety of artistic and cultural events have been held here, with only exception being the year when the Amphitheater roof was being constructed.

The Daxin Elementary School, Chunghwa Telecom Building, Huiwen Flower Market and a large number of trendy, exotic restaurants are all within easy walking distance.

This convenient transportation network and ease of access have undoubtedly made this neighborhood a top residential choice in Taichung.
