24 Horas (24 hours) is a Chilean newscast channel. It is broadcast by Televisión Nacional de Chile since 1990. The program is the successor to the newscast Noticias, which in turn replaced TV Noticias.

24 Horas (Spanish pronunciation: [bejntiˈkwatɾo ˈoɾas], 24 Hour) is a Spanish free-to-air news channel that was launched on 15 September 1997.

It produces news output and factual programmes for La 1, La 2 and TVE Internacional, and simulcasts most domestic news programmes aired on La 1.

It was initially available on the Vía Digital digital satellite package on the Hispasat satellite at 30° West, and was encrypted, and thus mainly aimed to Spain, although it could also be seen simulcasted by TVE Internacional at certain times of the day. However, it eventually started simulcasting on the Eutelsat Hot Bird and SES Astra satellite system in the clear, moving later to free-to-air digital transmissions on the same satellite at a later date.

Currently, the channel is available on the Astra 1KR and Hispasat 1D satellites at 19.2°E and 30°W respectively as part of the Digital + package for Spain only, on the Eutelsat Hot Bird satellite at 13°E for the whole of Europe, and the Hispasat 1C satellite at 30°W for the Americas until March 2006. Afterwards it will only be possible to receive TVE through Spanish packages offered by Dish Network and DirectTV in the Americas.

Since November 2005, it has also been available on digital terrestrial television in Spain. La 1 simulcasts the channel between 04:00 or 05:00 (local time) and 06:30. During the public holidays or the summer break, it simulcasts until 10:05.

In Europe, it is available free-to-air on Eutelsat Hot Bird 13° East. Due to economic reasons, it moved its satellite distribution for Europe to Astra 19.2°E alongside TVE Internacional and the RTVE radios (RNE Radio Nacional, RNE Radio Clásica, RNE Radio 3, RNE Ràdio 4, RNE Radio 5, Radio Exterior) between January 2014 and January 2020. As of January 1, 2020, it is also available terrestrially in Puerto Rico over the second subchannel of television station WORA-TV.
