The Aid Maker application can be added to any MySpace profile and raises money for charities while users shop online.
By shopping through affiliated websites, such as eBay, Amazon or the Apple Store, a proportion of the profit goes directly towards funding a charity, such as Save the Children, the Red Cross of Amnesty International.
Jamie Kantrowitz, senior vice-president of marketing, entertainment and content at MySpace International, said: "Social action on the web is a thriving environment and MySpace is driving this on a global scale.
"We support our users to promote the causes they are passionate about, which is why we've partnered with aGoodCause to give Myspacers a unique opportunity to take action and make a real difference."
The partnership has been launched in seven countries including the UK, France, Germany, Italy, the Netherlands, Sweden and Denmark.
