Zigzag is an unincorporated community in Clackamas County, Oregon, United States.

[1] Pioneer Joel Palmer crossed the deep ravine of Zigzag Canyon near the timberline on Mount Hood on October 11, 1845.

[3] He described the crossing in his journal: The manner of descending is to turn directly to the right, go zigzag for about one hundred yards, then turn short round, and go zigzag until you come under the place where you started from; then to the right, and so on, until you reach the base.The Zigzag River is no more crooked than adjoining streams, therefore the stream was most likely identified to fellow travelers on what was to become the Barlow Road by the manner of crossing and not for an especially irregular alignment.

The 1935 Zigzag Ranger Station is listed on the National Register of Historic Places (NRHP).

St. John the Evangelist Roman Catholic Church, another NRHP property, was formerly in the Zigzag area.
