This is a community wiki post for collecting answers that are just a literal that the language in question prints out automatically. Because it's a community wiki, feel free to edit it to add more languages where it works.

This program works in:

• PHP
• HTML (arguably not a language)
• Jelly
• 7 (more interesting, because the program's interpreted as both data and code; the first 3 prints the data, the rest of the program is useless stack manpulation)
• CJam
• Japt
• Carrot

Assuming the final newline is considered irrelevant, this is valid in quite a few more languages:

• 05AB1E
• 2sable
• GolfScript
• PowerShell
• GNU M4
• Pyth
