The '''Henkes Islands''' are a group of small islands and rocks {{convert|2|nmi|km|0|disp=flip}} in extent, lying {{convert|1|nmi|km|0|disp=flip}} southwest of [[Avian Island]], close off the southern extremity of [[Adelaide Island]], Antarctica. The islands were discovered by the [[French Antarctic Expedition, 1908–10]], under [[Jean-Baptiste Charcot]], and named by him for one of the Dutch directors of the [[Magellan Whaling Company]] at [[Punta Arenas]]. Charcot applied the name to the scattered rocks and islands between [[Cape Adriasola]] and [[Cape Alexandra (Adelaide Island)|Cape Alexandra]], and the name was restricted to the group described by the [[UK Antarctic Place-Names Committee]] (UKAPC) following definitive mapping by the [[British Antarctic Survey]] (BAS) in 1961 and the [[British Royal Navy Hydrographic Survey]] (BRNHS) in 1963.<ref name=gnis-HI/> All of the islands in the group were named by UKAPC.

Worth Reef is an arc of rocks forming the northernmost part of the Henkes Islands.<ref name="gnis-WR" /> They were named for Acting Corporal David A. Worth of the BRNHS.<ref name="gnis-WR" /> The easternmost of the Henkes Islands is Biggs Island, actually a small island. It was named for Thomas Biggs, a [[Falkland Islander]], coxswain of the launch of [[RRS John Biscoe (1956)|RRS ''John Biscoe'']], which was used by the BRNHS to chart this island in 1963.<ref name="gnis-BI" /> Between Biggs and Preston islands are four rocks collectively known as the Dean Rocks, named for Engineer Mechanic [[Thomas Dean (mechanic)|Thomas Dean]] of the BRNHS.<ref name="gnis-DR" />

The largest of the Henkes Islands is Preston Island, which was named for Frank Preston, BAS officer in charge at Adelaide station.<ref name="gnis-PI" /> The second largest island in the group is Crouch Island, surveyed by BRNHS in 1963, and named for [[Alan Crouch]], BAS general assistant at Adelaide station.<ref name="gnis-CI" /> Both were members of the first party to winter at Adelaide station, 1961–62.<ref name="gnis-PI" /><ref name="gnis-CI" />
