The 2011 Power Horse World Team Cup was a tennis tournament played on outdoor clay courts.
After ARAG discontinued sponsorship for the event and organizers failed to find a new sponsor, the 2011 edition of the tournament was cancelled.
However a new sponsor (Power Horse) was found in January 2011, and so the 2011 edition of the Cup took place between May 15–21.
Leading the team roster, the defending champions, Argentina, also won in 2007, 2002 and 1980.
Germany won the Cup with a 2–1 win against Argentina, the double match being decisive where Philipp Petzschner and Philipp Kohlschreiber defeated Juan Ignacio Chela and Máximo González 6–3, 7–6(7–5).
