The Swan Lake Fire was a large lightning-caused wildfire that burnt between Sterling and Cooper Landing on the Kenai Peninsula in Alaska from June 5, 2019, until the autumn of that year.

The southwest corner of the fire was approaching the Sterling Highway corridor, which is the sole major road providing access to the western peninsula.

Wildlife refuge and national forest managers closed several areas in response, motorists were warned of poor conditions and delays, and residents of Cooper Landing were advised to be prepared to evacuate.

[16] By late August the fire had spread closer to Cooper Landing and residents were put on a "set" warning, meaning they should be ready to evacuate at any time.

[18] By September 1, the weather had changed to the more usual damp, rainy conditions normal for that time of year and fire growth had slowed considerably.

Pilot car operations continued on the Sterling Highway and travelers were still warned to expect long delays during the Labor Day holiday weekend.

[19] By the seventh, rain had helped considerably and much progress was made in constructing control lines, although hot spots remained on the western edge in hard to access areas which were targeted by helicopter operations.
