Cardiff City have renamed the Canton stand the Croeso stand as part of a sponsorship package with the Welsh Government.
The £110,000 deal will run from August 2013 to May 2014.
The Welsh Government says it will also purchase TV advertising time with Sky Sports during live Cardiff City games.
The Welsh Government has had an ongoing sponsorship investment with Swansea City since the team was promoted to the Premier League in 2011.
It says the aim of the new deal is to promote Wales to a worldwide audience.
It will also see Visit Wales branding inside and outside the stadium, pitch-side advertising boards, the use of a hospitality box and advertising opportunities on stadium screens and in the car park.
Economy Minister Edwina Hart announced the deal at the Cardiff City Stadium on Thursday with manager Malky Mackay and Craig Bellamy.
She said: “Cardiff City’s fantastic achievement in reaching the Premier League has provided a unique chance for promoting Wales to a worldwide audience. We want to ensure that every visitor to Cardiff next season and the millions of television viewers in more than 200 countries worldwide know what a warm welcome awaits them in Wales.
“Cardiff is a dynamic, international city and a great place to visit and do business. This partnership will help us promote tourism and business opportunities in the capital city and across the whole of Wales.”
Mackay added: “The warmth my family and I felt on coming to Wales just over two years ago will forever stay with us.
“Cardiff is a fantastic city and the Welsh way of life is immensely endearing. I’m incredibly proud to be Cardiff City manager and to be leading us into the Premier League.
“We now have a platform on which to demonstrate what we do as a club, city and country on a global level.”
All the branding and advertising will be in place for Cardiff City’s first home game in the Premier League against Manchester City on August 24.
A recent economic impact assessment study of Swansea City’s first season in the Premier League found that it was worth £58m to the local economy, and more than 400 jobs were created or safeguarded.
