Definitely, but not as easily.
A virus can spread without internet through a LAN (Local Area Network) if you have one, through transferred files, or through removable media.
If your computer is connected to a local network which links multiple computers to each other, but not the Internet, the virus may be able to jump from one computer to the next within the LAN. This can be prevented by disconnecting the infected computer from the LAN.
If you copy files from an infected computer, they can also be potentially infected. From my experience, it seems that images are targeted more than most other kinds of files, but almost anything can be infected. Non-executable encrypted files are probably the safest, and compressed files, especially those in less common formats, like .rar or .7z. Remember, though, nothing is completely safe.
Removable devices can also be infected. While it is nearly impossible for your mouse of keyboard to be infected, some removable devices are fairly vulnerable. Flashdrives and external hard drives are the most common to be infected. Many viruses will only be able to spread from that removable device if the infected item is run. This can happen if your device autoruns (which has been disabled on most Windows computers since Windows XP), or if you open an infected picture of document, or run a portable program. Never run an executable that you do not recognize.
Optical disks (CDs and DVDs) are safer from this, but in theory, if not in practice, the virus could burn extra information to the disk, and you could be infected by the disk's autorun (which is NOT disabled on most computers) or by running the infected item.
Removable devices can also be tampered with such that they install the virus when they are connected. This would occur when the device driver is installed. I am unsure if a virus has any way to do this, or if it must be done manually by an individual.

No. Your Computer does NOT have to be connected to the Internet to run a virus. Any contaminated or corrupt file can infect your computer any time it is open, run, or executed.
