Kamøyfjorden (Northern Sami: Gáhpevuotna) is a fjord on the northeastern side of the large island of Magerøya in Nordkapp Municipality in Finnmark county, Norway.

The 14-kilometre (8.7 mi) long fjord runs from the Barents Sea southwest with two smaller fjords that branch off: the Skipsfjorden flowing to the south and the Duksfjorden flowing to the west.

[1] The mouth of the fjord spans between Beinviknæringen in the northwest and the Helnes Lighthouse in the southeast.

The Kamøyfjorden reaches a depth of 153 metres (502 ft) at its deepest point, just northwest of Helnes.

The European route E69 highway runs along the innermost part of the fjord, along the south side of Skipsfjorden.
