Sandglass (Korean: 모래시계) is a South Korean television series. It is one of the highest-rated Korean dramas in history, and is also considered one of the most significant. Written by Song Ji-na, directed by Kim Jong-hak and produced by their own company Jcom, it aired on SBS in 1995 in 24 episodes.

A depiction of the tragic relationship among three friends affected by the political and civilian oppression of 1970s and 1980s Korea, the series mixed politics, melodrama, and action. It recorded a peak rating of 64.5%, the fourth highest of all time, and launched its leading trio of Choi Min-soo, Go Hyun-jung, and Park Sang-won into stardom. Its reenactment of the Gwangju Uprising (interspersed with archival video footage) has been called one of the most realistic and memorable moments in Korean TV history.
