ROCS Tian Dan (田單, PFG-1110) is the eighth ship of the Cheng Kung-class guided-missile frigates of the Republic of China Navy, which was based on the Oliver Hazard Perry class of the United States Navy. Tian Dan was laid down in December 2001, launched on 17 October 2002, and commissioned on 11 March 2004. The relatively large time gap between the construction of Tian Dan and the previous Cheng Kung-class frigate, Chang Chien, can be accounted by that Tian Dan was not intended to be of the standard Cheng Kung design. Initially, the design of Tian Dan was going to be modified to fit a lighter version of AEGIS that later became SPY-1F, and the drawings looked very much like the Spanish Navy Álvaro de Bazán (F-100) class frigates. However, due to uncertain risks at the time, such as the need for ROCN to bear the full cost of the SPY-1F design, and concerns of putting such a system on such a small hull, forced ROCN to abandon this ambitious plan by mid 1990s. The original plan called for three more SPY-1F AGEIS type frigates, in addition to Tian Dan. Álvaro de Bazán can be seen as a realization of this plan with SPY-1F system.

Like her sister ships, Tian Dan was constructed by China SB Corp., at its primary shipyard in Kaohsiung City, Taiwan, Republic of China. But this ship is different from her sister ships by not having the two Bofors 40mm/L70 guns installed. Tian Dan is named after Tian Dan, a general of the Warring States period.

As of 2015, Tian Dan is home ported at ROCN Tso-Ying naval base.
