Yes. Set required to false.

I landed here looking for a way of specifying multiple optional arguments. Based on the examples above, I did:
@click.command()
@click.argument('size', required=False)
@click.argument('flavour', required=False)
def order_pizza(size, flavour):
print "Ordering {} ({})".format(size, flavour)
This gives you two positional arguments, both of which are optional.

I think the documentation could make this flag more obvious, by putting a section on the Arguments page.

Answered my own question!
Seems you beat me too comment mitsuhiko :)
Just saw the required
flag in http://click.pocoo.org/api/#parameters
If anyone else stumbles across this, as a quick ref, it's a simple as...
@cli.command()
@click.argument('names', nargs=-1, required=False)
def greet(names):
if len(names) == 0:
print "hello all"
else:
print "hello {}".format(" and ".join(names))
from click.
JFTR: if nargs is -1 then the argument becomes implicitly "non required". An empty sequence still works.

This helped me today. :)
