This is a weird one.
I've installed the EPEL for CentOS 6 via
# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
The tried to install HAProxy:
# yum update
# yum install haproxy
But receive:
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
* base: ftp.heanet.ie
* epel: fedora.mirror.nexicom.net
* extras: ftp.heanet.ie
* updates: ftp.heanet.ie
Setting up Install Process
No package haproxy available.
Error: Nothing to do
Can't figure out why haproxy is not found! Help?

The haproxy package has been removed from EPEL because it is now included with RHEL 6.4 (and will be in derivative distributions after they build 6.4).
If you need it now, you can obtain Red Hat's 6.4 SRPM and rebuild it on your system (the same way CentOS will shortly). For example:
Otherwise you can wait for CentOS 6.4 and then it will be available through the base repository.
