Abstract: Extending the notion of Haagerup property for finite von Neumann algebras to the general von Neumann algebras, the authors define and study the $(**)$-Haagerup property for $C^{*}$-algebras in this paper. They first give an answer to Suzuki's question (2013), and then obtain several results of $(**)$-Haagerup property parallel to those of Haagerup property for $C^{*}$-algebras. It is proved that a nuclear unital $C^{*}$-algebra with a faithful tracial state always has the $(**)$-Haagerup property. Some heredity results concerning the $(**)$-Haagerup property are also proved.
