Rhonda Wellington Lloyd is a fictional character in the animated series Hey Arnold!. She was voiced by Olivia Hack for the series' entire run.

Note: Some minor plot details follow.

Rhonda considers herself one of the most fashionable students at school. However, she also falls into the same convention of several animated characters, namely, that she wears the same clothes (red shirt, black pants) all the time (see Limited Wardrobe at Television Tropes and Idioms). Her parents Brooke and Buckley (Lori Alan and Sam McMurray , respectively) are wealthy, and she frequently holds parties at her house ("Helga's Makeover", "Hey Harold!", "Cool Party", "Helga's Masquerade").

However, Rhonda does have her flaws: she has been known to be "pushy, self-obsessed and materialistic" ("Polishing Rhonda"), and she has strong discrimination against so-called geeks, such that she forces them to the back of the bus ("Rhonda's Glasses") and maintains a list of cool kids and geeks ("Cool Party"): she and Arnold are the only major characters on the former list, and Gerald (ostensibly, among the cooler kids on the show) is on the latter list (she's had a personal grudge against him ever since he ran against her for class president).

Whereas Arnold and Helga's best friends (Gerald and Phoebe, respectively) also have major character status, Rhonda's best friend Nadine (Lauren Robinson ) is a relatively underused character: she only had speaking roles in 7 stories, one each in the show's final two seasons ("Dinner for Four" in season 4 and "Rhonda Goes Broke" in season 5), and no focus roles. Nadine's most distinct feature is her spider-shaped braids, which is somewhat fitting, since Nadine is the fourth-grade nature expert, with a special interest in insects (she has a pet tarantula and can sometimes be seen with a butterfly net).

Rhonda's glasses

Among the most blatant gaps in Hey Arnold!'s continuity concerns Rhonda getting glasses (rather blocky ones, at that) after getting a bad result on her optical examination, rendering her a geek, the very type of person she has always discriminated ("Rhonda's Glasses"). She had never shown any signs of optical problems before this ep, however. Also, by the end of the story in question, she has a more fashionable pair. However, from her next appearance onwards (in production order "New Teacher", in US airing order "What's Opera, Arnold?"), she appears as she had appeared before that story (i.e., without glasses, blocky or otherwise).

"Cool Party" seemed to be most appropriate story to feature her glasses again, since it also deals with her constant discrimination against geeks, however, they're nowhere to be seen, especially when she's actually at Arnold's party for geeks herself (where her "blocky" glasses would have seemed perfectly welcome).
