What is TrueCrypt?
[TrueCrypt is not exactly "Open Source", but the source is available. See the reviews to get more information.]
TrueCrypt is a disk encryption software for Windows Vista/XP, Mac OS X, and Linux.
Creates a virtual encrypted disk within a file and mounts it as a real disk.
Encrypts an entire partition or storage device such as USB flash drive or hard drive.
Encrypts a partition or drive where Windows is installed (pre-boot authentication).
Encryption is automatic, real-time (on-the-fly) and transparent.
Parallelization and pipelining allow data to be read and written as fast as if the drive was not encrypted.
Encryption can be hardware-accelerated on modern processors.
Provides plausible deniability, in case an adversary forces you to reveal the password:
Hidden volume (steganography) and hidden operating system.

Discontinued
Currently unmaintained. Last version, TrueCrypt 7.1a, is still available for download and development has continued via the forks VeraCrypt and CipherShed. "The development of TrueCrypt was ended in 5/2014 after Microsoft terminated support of Windows XP. Windows 8/7/Vista and later offer integrated support for encrypted disks and virtual disk images."

Truecrypt is Secure - It Has Passed the Final Audit
The disk encryption software Truecrypt, a popular tool that was endorsed by Edward Snowden, has passed a full source code security audit. This comes on the heels of the developers of the app mysteriously quitting the project and recommending that people use a questionable Microsoft solution.
The initial audit of the bootloader was performed by iSec who found only minor issues with the software that would not compromise security. The full report of the phase I audit is here:
https://opencryptoaudit.org/reports/iSec_Final_Open_Crypto_Audit_Project_TrueCrypt_Security_Assessment.pdf
The phase II audit was completed by NCC. The full report can be read here:
https://opencryptoaudit.org/reports/TrueCrypt_Phase_II_NCC_OCAP_final.pdf
This is the best encryption software I've ever seen, out of a dozen of encryption software I've tried. Finding this application was a real stroke of luck (Thanks to alternativeTo). With a novice-friendly interface and explanatory wizard it provides a great way to encrypt existing partitions/drives and to create new encrypted file containers. A TrueCrypt file container can function as an ordinary volume by mounting it as a virtual disk and the concept of hidden volumes takes data security to a whole new level. On-the-fly encryption provides access to the data while keeping it encrypted at the physical level. If there were a rating system here, I would give it 5 out of 5.
Truecrypt is depracated. Veracrypt has inherited the code, added new functionality and improved security. Don't use Truecrypt, use Veracrypt; it's still open source, free and every bit as useful.
Truecrypt did pass a security audit, but since then vulnerabilities have been found. VeraCrypt, which also open source, has taken on the TrueCrypt code and improved it, including in terms of security. VeraCrypt is backwards compatible with TrueCrypt containers. You should use VeraCrypt from now on, and convert your containers to the VeraCrypt format.
You can actually mount Truecrypt volumes in Linux without installing it, but with help of cryptsetup. Mounting an NTFS partition would go something like this:
sudo cryptsetup open --type tcrypt /dev/sdc5 cryptmountpoint
sudo mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1001,gid=1001,dmask=0077,fmask=0177" "/dev/mapper/cryptmountpoint" "/media/actualmountpoint"
Then when you're done with it:
sudo umount /media/actualmountpoint
sudo cryptsetup close cryptmountpoint
Pretty easy, if you know how. ;)
Of course, you need to replace the devices and mount points with your own values.
As of May 2014 TrueCrypt is no longer supported or maintained. You can read all about it on Wikipedia:
http://en.wikipedia.org/wiki/TrueCrypt
The official website recommends switching to use existing encryption methods built-in with most modern operating systems. In view of this the final release will only allow you to decrypt your old TrueCrypt volumes in order to migrate to other encryption tools.
However there is a large number in the open source community with an interest in continuing the tools development under a new name and license in the near future. In the mean time the most recent full-featured version (7.1a) has been made available on various 3rd party sites and GitHub: https://www.grc.com/misc/truecrypt/truecrypt.htm https://github.com/AuditProject/truecrypt-verified-mirror
Yes, TrueCrypt 7.1a works perfectly without backdoors. But do not trust TrueCrypt 7.2 as suspicion arose that 7.2 version's setup looks after the earier 7.1a version's setup.exe file and modifies (infects) it with a backdoor. Available checksums' trustability is also questionable as the related websites' archives are all deleted (and present content could be modified too). So one can only trust TrueCrypt 7.1a burned to CD/DVD before 2014, or program version that can be verified by a checksum from a file that had written to DVD before 2014. (Although REAL write time of a DVD is also known by only the person who has done it.)

Free, but...
When one mean's "free" as in:
"Free at point of downloading": Yes
["Libre software definition"][1]: No
Be advised that according to the Fedora Project's "[Forbidden Items][2]" page:
This is indeed true as it states in the [licence][lic] (Section VI.2):
