Xiluo Township, also written Siluo Township, is an urban township in Yunlin County, Taiwan. It lies in the western part of the county, in the broad alluvial plain of central-western Taiwan.
Xiluo is best known for the Xiluo Bridge, a long road bridge spanning the Zhuoshui River and linking the township with Changhua County to the north. Completed in the 1950s, it was for a time the longest bridge in Taiwan and remains a local landmark. The township is also associated with Xiluo pomelo, a variety of citrus grown in the surrounding farmland.
Its economy has traditionally rested on agriculture, with rice and fruit among the main crops, and the township serves as a small service and market centre for the surrounding rural area.
