Jaijaidin (Bengali: যায়যায়দিন Jaejaedin) is a Bengali-language daily newspaper published from Dhaka, Bangladesh.

It came into fame during the 1980s because of its modern outlook and strong stance against the military ruler Hossain Mohammad Ershad.

The Monroe Studio is used for staged photo shoot for the newspaper and for recording television programs.

It is the place for the popular entertainment article "10 minutes at the Che Café".

Jaijaidin first introduced special issues with the articles from mass readers.

Beside introducing Valentine's Day this was the first Bangladeshi news publication to have its own website.

As a weekly the Jaijaidin first implemented the idea of Reader's Poll to elect the most popular performing artists.
