Here are a few contenders:
* The "Avisa Relation oder Zeitung" (1605), published in Germany. This is considered by many to be the first regularly published newspaper. However, it was not a daily publication and it's unclear how long it actually ran for.
* "The Oxford Gazette" (1665), published in England. This was the first regularly published newspaper in English, though it only lasted 23 issues before being renamed to the "London Gazette".
* "The London Gazette" (1665), published in England. This is the longest running newspaper in the world, though it has been published under various titles throughout its history.
Ultimately, there is no single definitive answer to the question of the oldest newspaper. It depends on how you define "newspaper" and "oldest". However, these three publications are all considered to be among the earliest and most important newspapers in history.
