The funding, led by Bain Capital Ventures with additional reinvestment from the company's existing investors Sequoia Capital, Greylock Partners, and Bessemer Venture Partners, is LinkedIn's fourth and largest round of funding to date.
According to Linkedin, the latest investment values the company at $1 billion.
The announcement comes as the company, which claims 23 million members worldwide, said it plans to expand its presence in the European market.
Kevin Eyres, European managing director at LinkedIn, said: "Europe is an integral part of LinkedIn's growth strategy. The new funds will enable us to invest more heavily in the European market - a geography for whom networking and business knowledge-sharing continues to accelerate and will help our members derive more value from their network so that each individual and business can more effectively compete on the global market."
Jeffrey Glass, venture partner at Bain Capital Ventures, said: "Our investment in LinkedIn is based on the company's opportunity, solid and diversified business model, smart strategy for growth and strong management team."
