24 Horas al Cierre

24 Horas al Cierre (previously called 24 Noche and ) is the late night edition of 24 Horas, flagship news program of TVN Chile. It currently has the longest timespan with independent branding out of TVN's newscasts: from 1996 to 2023, though TVN's many former newscasts did have late night editions starting with Noticiero in the early 1970s.

===1995–1996 (main), 1997–2002 (holiday breaks)===
Despite Medianoche being launched in 1996, the program initially had holiday breaks, so the Edición Nocturna de 24 Horas continued as a substitute during the southern hemisphere's summer months only.
===2003–2004 (holiday breaks)===
In 2004, Edición Nocturna de 24 Horas merged with Medianoche.
