What is the name of Tom Cruise's third wife?

Tom Cruise's third wife was Katie Holmes.

Cruise and Holmes began dating in 2005 after meeting through Hollywood connections, and their highly public relationship quickly attracted intense media attention. They married on November 18, 2006, at Odescalchi Castle in Bracciano, Italy, in a ceremony associated with Scientology.

Holmes was Cruise's third wife. He was previously married to actress Mimi Rogers from 1987 to 1990 and actress Nicole Kidman from 1990 to 2001. Cruise and Holmes have one child together, their daughter Suri, who was born in 2006.

The marriage ended when Holmes filed for divorce in 2012. Because Cruise's relationships and marriages were heavily covered by the press, a common mistake is to count long-term partners who were never his spouses. The question asks specifically for his third wife, making Katie Holmes the canonical answer.
