It means that in 2013/14, for the sixth time in eight seasons, there is to be no increase in Barclays Premier League and European competition knockout-phase tickets at the club.
Previous prize freezes covered the period between 2006 to 2010. Next season's tickets will be the same as 2011/12 levels, covering season tickets, individual match tickets and hospitality lounges.
The Blues, European champions in 2012 but currently fighting for Champions League qualification for next season, say each of the three price categories will remain unaltered for Premier League games, while the policy of discounted tickets for all non-hospitality seats for FA Cup and League Cup matches will continue next term.
Chief executive Ron Gourlay said on the club's official website: "Economic conditions remain tough for many people and the club would like to thank our supporters for the consistently very good attendances we have had throughout this season.
"Financial Fair Play regulations are now having an impact on clubs across Europe, but it was our hope a year ago when we announced prices would not be raised that this decision could be extended.
"We are pleased this has proved possible for 2013/14."
