How do I leave a clan?

Go to embassy > my clan > members, find your own name and there should be a red X next to it, just click that.

You could do what BiohazarD said, the 'boring' way...

Or you could do it the 'macho' way, and start insulting your clanmates, especially your Force Commanders, Deputy Clan Leaders, and Clan Leader.

Start raiding, invading, liberating all their colonies, deposits, sectors, and Emitters of your clanmates and clan allies as well...

I'm sure it may result in a few warnings and such, but a sure way to leave a clan with some PvP as well...   ;)   lol

Don't forget to talk bad about them in regional chat too :P

@BiohazarD (7 April, 2015, 5:11 AM UTC):
That depends if you have any clan mates in regional chat, too

If it's a newer player joining a higher ranked clan, they probably won't have any.

kill them all
