觀音坑溪 是淡水河支流，河長6.2公里，源頭位於觀音山南側的凌雲禪寺附近，向東南流入台北盆地後，轉向東注入淡水河。
觀音坑溪原本注入淡水河的另一支流塭子川，後因拓寬淡水河道工程而炸毀獅子頭隘口，即變成現況之各自注入淡水河。
Guanyin Pit Creek
is a tributary of the Tamsui River, with a length of 6.2 kilometers. Its source is located near Lingyun Zen Temple on the southern side of Guanyin Mountain. The creek flows southeast into the Taipei Basin, then turns eastward to join the Tamsui River.
Guanyin Pit Creek originally flowed into Wenzi Creek, another tributary of the Tamsui River. However, due to a river widening project on the Tamsui River, the Shizitou Gorge was demolished, resulting in the current situation where both creeks separately flow into the Tamsui River.
