Apple - Is there a way to copy the link URL in Safari (Mac OS X) without using right click?

Select Command-L That will highlight the URL field Then just select Command-C to copy.

This is the quickest keyboard shortcuts I have found.

Depending on what you are trying to do with the link, it may be sufficient to drag it. If you click and drag a link in Safari, you can drop it in many places and get the desired functionality. For example, if you drop it in a text editor, it will drop the link URL (for plain text) or a formatted link using the title from the page. If you drop it on your desktop, you will get a webloc file. If you drop it on the Safari URL bar or tab, that tab will load the link.

If you really need to copy the link, one possibility is to use spotlight as a easy-access text field. Start dragging the link, hit Command+space (or whatever you have it set to) to pop up spotlight, drop it in the search field, and copy.
