CBS This Morning (CTM) is an American morning television program that aired on CBS from November 30, 1987 to October 29, 1999, and again from January 9, 2012 to September 6, 2021. On November 1, 1999, the original incarnation was replaced by The Early Show, which was replaced by the second incarnation of CBS This Morning on January 9, 2012.

The second incarnation emphasized general national and international news stories and in-depth reports throughout each edition, although it also included live in-studio and pre-taped interviews. The format was chosen as an alternative to the soft media and lifestyle-driven formats of competitors Today and Good Morning America following the first hour or half-hour of those broadcasts, in an attempt to give the program a competitive edge with its infotainment format. It was the 10th distinct weekday morning news format aired on CBS since 1954, and the ninth attempt to do so since CBS resumed programming in that time slot since 1963. For all but a few periods since 1963, CBS has historically placed a distant third in the ratings among the network weekday morning shows.

On August 31, 2021, CBS announced that the weekday program would be replaced with the reformatted CBS Mornings effective September 7, while the Saturday edition of CBS This Morning was renamed CBS Saturday Morning on September 18, 2021, completing the transition.
