SK Group
South Korean conglomerate
SK Group (Korean: SK그룹; 에스케이그룹) is a South Korean multinational manufacturing and services conglomerate headquartered in Seoul. A chaebol (Korean family-owned conglomerate), SK Group is the second largest such conglomerate by revenue in South Korea, after Samsung Group. Through a number of subsidiaries, it is engaged in various businesses, including manufacture of AI semiconductors, flash memory, deep tech investment and miscellaneous information technology, chemicals and petrochemicals, as well as providing telecommunications services worldwide among its other less notable ventures.
The conglomerate is composed of 186 subsidiaries and affiliates that share the SK brand name and the group's management culture, named SKMS (SK Management System). It changed its name from Sunkyong Group (선경그룹; 鮮京그룹) to SK Group in 1998. The group is controlled by the estate of Chey Tae-won through a holding company, SK Inc. The cornerstone of SK Group is its energy and chemicals division.
History
Formation and early production
As with many other chaebols, SK Group's chairmanship was 'inherited' from father to son: from its late founder Chey Jong-hyon to its present chairman Chey Tae-won (eldest son). Chey Tae-won was married to the daughter of the former South Korean President Roh Tae-woo until 2015.
SK Group began when the current founders acquired Sunkyong Textiles from the South Korean government as abandoned property of Japan in 1953, following the Korean war armistice.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q494158. VIAF identifies the subject as 171193956. The Library of Congress control number is sh2023002576. 2 of 6 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank.

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
