The men, all from Birmingham, were arrested as part of a major operation carried out by the West Midlands Counter Terrorism Unit, West Midlands Police said.
The force said four men have been charged with preparing for an act of terrorism in the UK, and two more with failing to disclose information. One of those two was also charged with terrorist fundraising.
All six, who are aged between 25 and 32, will appear at West London Magistrates' Court on Monday.
