|Affiliates|| James Carter (Partner)|
|Portrayed by||Elizabeth Peña|
Tania Johnson is the LAPD's bomb squad expert and sometimes partner to Carter. She doesn't like that Carter prefers to work alone, as he's the only cop in the department without a partner. It was secretly hinted that she had romantic feelings for Carter as he teases her about it several times in the film. She could be seen later in the film trying to practice how to disable a bomb in a training room. During the climax she help defuses the C4 vest that Soo-Yung was strapped to which saved her and she gives the vest to Lee ordering him to get rid of the vest as the remote could still set it off.
Johnson has an apartment in Los Angeles and in a deleted scene when Lee and Carter arrive at her home she gives them two tuxedos for Consul Han's Chinese Art Exhibition at the Los Angeles Convention Center.
- It is unknown why Johnson didn't appear in the sequels. Elizabeth Peña was not contacted to reprise her role or mainly she might have moved on to other film projects.
- During filming of Rush Hour Elizabeth Peña played a prank on Brett Ratner in which she appeared on the set wearing nothing but her character's bomb squad vest. According to Peña, she thought Ratner would laugh, but instead, he was extremely nervous and embarrassed.
