Tavleøya (English:
Slate Island) is one of
Sjuøyane, north of
Nordaustlandet. The
island lies about 1 km west of the northern point of
Phippsøya, separated by Marmorsundet (English:
The Marble Sound), and about 7 km south of
Vesle Tavleøya. Two smaller
skerries to the northwest of Tavleøya are named
Kluftholmen.
