In Navy CIS, it mainly revolves around the case of the current episode, teamwork, and the personal development of Team Gibbs. There is little focus on the romances. However, they exist, and we have the top 5 couples ranked here for you.
How did this ranking come about? Based on our binge-watching evenings with Navy CIS, Reddit, and the rest of the internet, we compiled the most notable relationships from the series. Included are romances from earlier seasons like Gibbs and Jenny Shepherd or later episodes, like Ellie and her (ex-husband) Jake.
We then checked the Google search volume of the respective couples using the website Keyword Tool. In this list, you will find the top 5 couples that were searched for the most according to the site between August 2024 and July 2025.
By the way, we would also like to know if you agree with the list. Feel free to leave a vote for your personal favorite couple here before it goes into the rankings:

Rank 5: Timothy McGee and Delilah Fieldings-McGee
The start in the top five, with 2,290 searches, is made by Timothy Tim
McGee and Delilah Fieldings(-McGee). The two meet in season 10 and date each other. Delilah works at the United States Department of Defense as a cybersecurity specialist. After a drone attack at a gala and subsequent emergency operations, she is in a wheelchair.
In season 14, the two get engaged and later marry. Their small family has also grown: Twins John McGee II and Morgan McGee keep them quite busy. However, he and Delilah are actually not the most popular pairing for Tim.
