Christmas Island District High School (CIDHS) is a public co-educational early learning, primary, and high day school located in Christmas Island, a territory of Australia.

As of 2019[update] the school served approximately 235 students from Kindergarten through to Year 12.

Landcare recognised the school's efforts to clear a 90-metre (300 ft) stretch of Greta Beach used as a nesting ground for the green turtle.

The beach area is one of the dirtiest on the island as it traps debris brought in by currents.

For these continuing efforts, the school was selected as a 2004 Western Australia Landcare Education Award Finalist.
