JOSM (Java OpenStreetMap Editor) is a desktop application originally developed by Immanuel Scholz and currently maintained by Dirk Stöcker. Its homepage is located at josm.openstreetmap.de.
Although it has a relatively steep learning curve, JOSM is popular among experienced editors thanks to its plugins and stability. There are other editors for OpenStreetMap data, like iD or Potlatch 2. JOSM is a feature-rich editor with an interface which can seem complex at first. If you are unsure which editor to use, see the Comparison of editors article.

Installation
JOSM can be downloaded from the JOSM homepage. Many Linux distributions offer JOSM packages. See JOSM/Linux. It can be run as a local Java installation or with Java WebStart, which causes the latest version to be fetched over the Internet each time the program is run. Java version 1.8, minimum, is required to run JOSM as of 2017. The site security certificates for JOSM WebStart are invalid and will generate multiple warnings during startup, requiring the user to accept exceptions several times before the program is ready to use.

Several good tutorials have been created and shared by the Humanitarian OpenStreetMap Team via YouTube:
JOSM Basics (1.5hrs, 2019)

Help with JOSM
The JOSM Help manual should provide more exhaustive in-depth explanations of each JOSM feature. It is intended to be used as a reference manual, rather than reading from end-to-end. It is also accessible by pressing F1 within the application (context sensitive help)
Bookmarklets
Open any relation from openstreetmap.org directly in JOSM.
javascript:(function(){id=location.href.match(/www\.openstreetmap\.org\/relation\/(\d+)/);if(id!=null){window.open('http://127.0.0.1:8111/load_object?objects=r'+id[1]);}else{alert('This is not a valid Openstreetmap.org relation page.')}})()
