Dzharylhach (Cyrillic: Джарилгач, also spelled as Dzharylgach; Crimean Tatar: Carılğaç) is a sand bank in Skadovsk Raion, Kherson Oblast near Crimea in Ukraine.

[1] To the west it stretches as a spit and as a shoal, which sometimes dries up, and connects to the continental portion of Kherson Oblast near the town of Lazurne.

Its area of 56 km2 and length of 42 km make it the Black Sea's biggest sand bank, located at the Karkinit Bay.

It is a habitat for wild boars, deer, mouflon, as well as numerous seagulls and cormorant, hunting crabs, raps whelk and shrimp.

In the spring of 2023, Russian forces covered the crossing to the island with sand, permanently connecting it with the occupied part of the Kherson Oblast of Ukraine.
