"Understand Your Man" is a 1964 single by Johnny Cash. The single went to number one on the country charts for six weeks. "Understand Your Man" also crossed over to the Top 40, peaking at number 35.

Cash borrowed parts of the melody from Bob Dylan's "Don't Think Twice, It's All Right".

"Understand Your Man" was also the last song Cash ever performed in front of an audience. It was the last song in his performance at the Carter Family Fold in Hiltons, Virginia, on 5 July 2003. Prior to singing it, Cash told the audience that at that point he had not performed it live in 25 years. (It was not, however, the final song he ever sang as, despite failing health, he continued to make studio recordings until late August 2003, shortly before his death.)
