Is this related to updating WP? If so, see:

Definitely clear you browser cache and cookies.
Then deactivate your plugins by renaming the plugisn folder.
Then, yes, change the name on your active theme’s folder.
Where there any changes that you made to the site prior to this happening? Your .htaccess file can also cause a redirect loop for wp-admin. This is useful for some people.
Can you login with http://www.yoursitename.com/wp-login.php, or does it give you the same error?
It is related to updating WP, yes. Around the same time I changed my site path so that it could reflect the main domain, and not the “work-in-progress” version that lived in a different folder.
I already went through deactivating the plug-ins and that didn’t work.
If I change the name on the active theme’s folder can I change it back later if that wasn’t the culprit?
WPyogi–from the “Settings>General” page.
This was a site that I redesigned. The person in charge of the server for the site redirected the home page there, and then from WordPress I redirected the site so that the subsequent pages wouldn’t reflect my “wp2” folder that the WordPress site was in.
I did this on a previous site and had no issues, but then again I wasn’t updating to a new version of WordPress at the same time.
Thing is, the site’s fine–it’s the admin/log-in I can’t access.
Hmm–if I can’t change them there, how come it worked for another WP site I did?
I posted that before I saw your reply above it – so I’m not sure exactly what you did (or what anyone else did).
All I know is that I updated WordPress to 3.7.1; no issues.
Changed the WordPress and Site Address in General Settings (and didn’t have any issues with this on another site that was a redesign)
After that, login issues with this “too many redirects” loop
I’m going through the checklist of things to troubleshoot and was about to rename my theme folder so that it would default to “twenty-twelve” (or thirteen) but I want to make sure I don’t lose anything in trying to go back to my current theme.

That’s helpful – so then we can assume (hopefully) that it’s not an update issue.

So what, exactly, did you or someone else change?
Did you move files? Have you reviewed –
