The Argentine Islands are a group of islands in the Wilhelm Archipelago of Antarctica, situated 5 nautical miles (9 km) southwest of Petermann Island, and 4 nautical miles (7 km) northwest of Cape Tuxen on Kiev Peninsula in Graham Land. They were discovered by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, and named by him for the Argentine Republic in appreciation of that government's support of to his expedition.
Lambda Island is an island lying immediately north-west of Delta Island in the Melchior Islands, of the Palmer Archipelago in Antarctica.

Delta Island is an island 1 kilometre (0.5 nmi) long, lying close southeast of Lambda Island and east of Alpha Island in the Melchior Islands, Palmer Archipelago. The name, derived from the fourth letter of the Greek alphabet, was probably given by Discovery Investigations personnel who roughly surveyed the island in 1927.

Alpha Island, also known as Isla Huidobro, is a small island lying between Epsilon Island and Delta Island in the Melchior Islands, Palmer Archipelago. Charted by Discovery Investigations in 1927 and named after the first letter of the Greek alphabet, in association with the names of other islands in this group. The island was surveyed by Argentine expeditions in 1942, 1943 and 1948.
Omicron Islands is a group of small islands and rocks which lie close southeast of Omega Island in the Melchior Islands, Palmer Archipelago. The name, derived from the 15th letter of the Greek alphabet, appears to have been first used on a 1946 Argentine government chart following surveys of these islands by Argentine expeditions in 1942 and 1943.
West Melchior Islands is a group of small ice-covered islands and rocks which lie west of The Sound in the Melchior Islands, Palmer Archipelago. The islands east of The Sound are called East Melchior Islands. The name was probably given by DI personnel who roughly surveyed these islands in 1927.

Pi Islands are two islands and several rocks which lie 2 kilometres (1 nmi) east of the northeast end of Omega Island among the Melchior Islands, Palmer Archipelago. The name, derived from the 16th letter of the Greek alphabet, appears to have been first used on a 1946 Argentine government chart following surveys of these islands by Argentine expeditions in 1942 and 1943.
The East Melchior Islands are a group of small ice-covered islands and rocks which lie east of The Sound in the Melchior Islands, Palmer Archipelago. The islands west of The Sound are called the West Melchior Islands. The name was probably given by Discovery Investigations personnel who roughly charted these islands in 1927. The islands were surveyed by Argentine expeditions in 1942, 1943 and 1948.
Epsilon Island in the Antarctic is a small island lying between Alpha Island and the southern extremity of Lambda Island in the Melchior Islands, Palmer Archipelago. The island was roughly surveyed by Discovery Investigations personnel in 1927. The name, derived from epsilon, the fifth letter of the Greek alphabet, appears to have been first used on a 1946 Argentine government chart following surveys of the Melchior Islands by Argentine expeditions in 1942 and 1943.
Fournier Island is a small island in the southern Schollaert Channel, lying 1 kilometre (0.5 nmi) off the eastern extremity of Anvers Island, in the Palmer Archipelago. The island was charted but left unnamed by the French Antarctic Expedition, 1903–05. The name appears on Argentine charts dating back to 1950, and honors the ship Fournier which took part in the Argentine Antarctic Expedition of 1947. In 1948 the vessel was wrecked in the Strait of Magellan.
Gamma Island is an island, 1.6 kilometres (1 mi) long, which marks the southwestern extremity of the Melchior Islands in the Palmer Archipelago. This island was first roughly charted and named "Ile Gouts" by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, but that name has not survived in usage. The current name, derived from gamma, the third letter of the Greek alphabet, was probably given by Discovery Investigations personnel who roughly surveyed the island in 1927. The island was also surveyed by Argentine expeditions in 1942, 1943 and 1948.
Theta Islands are several small islands and rocks which lie close west of Kappa Island at the west extremity of the Melchior Islands, Palmer Archipelago. The islands were roughly charted by Discovery Investigations personnel in 1927. The name, derived from the eighth letter of the Greek alphabet, appears to have been first used on a 1946 Argentine government chart following surveys of the Melchior Islands by Argentine expeditions in 1942 and 1943.
Tau Islands is a small group of islands and rocks which lie immediately off the northeast extremity of Eta Island in the Melchior Islands, Palmer Archipelago. The name, derived from the 19th letter of the Greek alphabet, appears to have been first used on a 1946 Argentine government chart following surveys of the islands by Argentine expeditions in 1942 and 1943.
