The siege of Johor of 1587 was a military operation in which Portuguese forces successfully sieged, sacked, and razed Johor, capital of its eponymous sultanate. The city would later be rebuilt at a different location.

In 1586 naval forces of Johor began diverting shipping to the Singapore Strait due to a lack of personnel available in Malacca. Malacca itself was threatened by a large Johor fleet, but it was driven back by the presence of heavily armed Portuguese galleons in its harbour.
