Kimberly Ann Hart is a fictional character in the Power Rangers universe. Played by American actress Amy Jo Johnson during the first three seasons of the show, plus on the two feature films of the franchise, Kimberly has the longest tenure of any female ranger in the series' history, and fourth overall. She is best remembered as the first Pink Ranger (pterodactyl) and first Pink Ninja Ranger from the first entry of the franchise Mighty Morphin Power Rangers. Kimberly was the Pink Ranger for nearly three years before she was written off the show as having given up her powers for good to Zordon's new pink ranger Katherine Hillard, to participate at the Pan Global Games in Florida. However, she would briefly return as the Pink Ranger on three occasions. She first returned during the Legendary Battle of Power Rangers Super Megaforce alongside former teammates Zack Taylor, Billy Cranston, Trini Kwan, and Jason Lee Scott. The five of them later fought alongside the Dino Thunder Rangers, Dino Charge Rangers, and the Grid Battleforce Rangers against Goldar Maximus in Power Rangers Beast Morphers. She also returned to fight a robotic version of Rita Repulsa with the other four original rangers and Tommy Oliver in Mighty Morphin Power Rangers: Once & Always. Johnson did not reprise her role for any of these appearances.

A reimagined version of Kimberly would appear in the 2017 reboot film, played by British actress Naomi Scott.

Kimberly is one of the original five Power Rangers chosen by Zordon when Rita Repulsa attacked Earth following her release from containment. She, along with her close friends Jason Lee Scott, Zack Taylor, Billy Cranston and Trini Kwan, was one of the five teens chosen by Zordon to receive a great power, drawn from the spirits of the prehistoric animals. Kimberly receives the Pterodactyl Power Coin and the Pterodactyl Dinozord, thus becoming the Pink Power Ranger. Kimberly starts the series as a stereotypical valley girl, but with a heightened awareness for her friends. Throughout the series, she is the member of the team most likely to fire off a sarcastic or witty retort. However, as the series progresses, she becomes a deeper and kind-hearted person, due to experiences such as switching bodies with the nerdy Billy Cranston and being turned into a punk after Baboo administers a potion to one of Kimberly's drinks. She also displays a cunning, clever and intuitive side, also inherited from her time in switching bodies with Billy.

Kimberly is a capable gymnast and was often shown training and using her abilities in fights against Rita's forces, as she fought with a blend of gymnastic maneuvers, elbows and kicks. She often uses the environment around her as a springboard for her attacks and is often needed to defeat monsters with visible weaknesses, such as the archery-based Snizzard and the Terror Toad. She also teaches dance classes at Angel Grove's Youth Center while using American Sign Language to interpret for a student with a disability. Kimberly is revealed to be proficient in many hobbies throughout the series, including designing and arranging the floral pattern for a parade float, being regarded as a great cheerleader throughout Junior High School and being able to sing and play guitar.

Ranger Slayer has not been a contender in any CBUB matches.
