Route 63 is a state highway on the island of Oʻahu in Honolulu County, Hawaiʻi, United States, that is one of three main highways passing through the Koʻolau mountain.

The highway passes through the Wilson Tunnel, and takes commuters from the towns of Kāneʻohe and Kailua on the windward (northeast) side of the island, through Kalihi Valley into Honolulu on the leeward (south) side of the island.

There is a runaway truck ramp on the highway.
