Jennifer Lopez: Feelin' So Good is the first long-form video by American singer Jennifer Lopez. It was released in the United States on DVD and VHS on November 7, 2000, by SMV Enterprises, the home media division of Sony's music and entertainment label. With a running time of 60 minutes, the video provides a documentary-style look at the launch of Lopez's music career, through a mixture of interviews, behind-the-scenes footage, music videos and live performances. The interview segments were conducted by Lopez's sister Lynda, who interviews not only Lopez, but also their mother, Benny Medina and Marc Anthony.

Beginning her career in musical theater, Lopez re-entered the music scene upon her portrayal of the title role in the Selena biopic of the same name (1997). The role inspired her to launch a career in music; critics deemed it risky, noting that if she was unsuccessful in doing so, it would be an embarrassment and could damage her career. During the production of her debut album, On the 6 (1999), Lopez was aware that she received her recording contract on the premise of having an already established name in the entertainment industry; her goal for the album was to prove she had musical talent. The success of her debut single "If You Had My Love" and On the 6 came as a surprise to critics; their release made the "popular actor even more popular", with both the music industry and the public becoming intrigued by "this woman who seemed to have so many different talents".

Jennifer Lopez: Feelin' So Good received generally favorable reviews from critics, although it was noted that it would be of no interest to those who were not fans of Lopez. It was additionally praised for showing the singer's transition from her acting career to a music career. The interview segments of the video were deemed to be "slick and promotional". In the United States, Jennifer Lopez: Feelin' So Good was certified as a Gold Video Longform by the Recording Industry Association of America (RIAA) for shipments of 50,000 units.
