— are American terms for journalism and associated newspapers that present little or no legitimate well-researched news while instead using eye-catching headlines for increased sales. Techniques may include exaggerations of news events, scandal-mongering, or sensationalism. By extension, the term yellow journalism is used today as a pejorative to decry any journalism that treats news in an unprofessional or unethical fashion.

The term is chiefly used in the US. In the UK, a roughly equivalent term is tabloid journalism, meaning journalism characteristic of tabloid newspapers, even if found elsewhere.
