Mary Christine Brockert (March 5, 1956 – December 26, 2010), known professionally as Teena Marie, was an American singer-songwriter, musician, composer, arranger, and producer. She was known by her childhood nickname Tina before taking the stage name Teena Marie and later acquired the nickname Lady Tee (sometimes spelled Lady T), given to her by her collaborator and friend, Rick James.

She was known for her distinctive soprano vocals, which caused many listeners to believe she was black. Her success in R&B and soul music, and loyalty to these genres would earn her the title Ivory Queen of Soul. She played rhythm guitar, keyboards, and congas. Teena Marie was a three-time Grammy Award nominee.

In 2004, while Teena Marie was sleeping in a hotel room, a large picture frame fell and struck her on the head. The blow caused a serious concussion that caused momentary seizures for the rest of her life.

On the afternoon of December 26, 2010, Teena Marie was found dead at her Pasadena home by her daughter, Alia Rose. On December 30, 2010, an autopsy was performed by the Los Angeles County coroner, who found no signs of apparent trauma or a discernible cause of death, and concluded she had died from natural causes. She had suffered a generalized tonic–clonic seizure a month before.

A memorial service was held at Forest Lawn Cemetery on January 10, 2011. Among those in attendance were Stevie Wonder, Deniece Williams, Smokey Robinson, Queen Latifah, LisaRaye, Sinbad, Tichina Arnold, Shanice Wilson, and Berry Gordy, Jr
