Emma Olivia Watkins (born 21 September 1989) is an Australian children's entertainer, dancer, singer, and actress. She is best known as the first female member of the children's group the Wiggles, which she was a member of from 2013 to 2021. Due to her popularity in the group, she starred in her own spinoff series as a solo Wiggles performer, titled Emma!. After departing the group, she debuted her own children's entertainment character, Emma Memma, in 2022. She released her first solo children's music album in September 2022, which received an ARIA Award for Best Children's Album in 2023.

Watkins has also appeared in reality television series including The Masked Singer, The Amazing Race Australia and a Christmas special of Lego Masters Australia. She narrated the children's series Reef School, and hosted Teenage Boss: Next Level in 2024.

Watkins started ballet when she was four. She saw the Wiggles perform Irish dancing and later studied other styles of dance, including jazz, hip hop, tap and contemporary. She attended The McDonald College, a performing arts school, won a full scholarship at the Sydney Film School, and completed a certificate specialising in musical theatre at ED5 International in Sydney. Watkins earned a master's degree in Media Arts and Production at the University of Technology Sydney. She has taught dance to children since she was in high school. She has also performed in Bollywood films, learned drums and other percussion instruments, was crowned Miss Granny Smith Apples in 2009, and was learning Auslan, the Australian sign language, by 2012. As of 2021, she was doing her PhD research on sign language and dance.

In 2010, Watkins began performing with the Wiggles, first as Fairy Larissa and then as Wags the Dog, Dorothy the Dinosaur, and as a Wiggly Dancer. She used her film skills during tours with the group, providing them with video and editing services. In May 2012, the Wiggles announced that Watkins would become the first female Wiggle, replacing founding member Greg Page as the Yellow Wiggle. The original members stated that they chose Watkins because she was the most qualified for the job, and commented that it was "a strategy for marketing the Wiggles into the next generation".

Lisa Tolin of the Associated Press called Watkins a strong role model for girls, and reported that her fans came to concerts dressed like her and that they gave her homemade bows, which had become part of her signature look. Because of her popularity, the company produced a new television series titled Emma!, featuring Watkins as a solo performer, which aired in 2015. Up to 80% of the audience at Wiggles concerts would emulate her costuming and wear yellow; by 2021 it was estimated that 50% of the group's merchandising was specific to the "Emma" brand.

In September 2019, it was announced that Watkins would host weekend afternoon programs on Sydney and Melbourne radio station smoothfm. In October 2020, Watkins appeared in the music video for "Back 2 Back" by Samantha Jade. At the 2020 ARIA Music Awards in November, she joined an ensemble of Australian women singers to perform "I Am Woman" as a tribute to its singer and songwriter, Helen Reddy.

It was reported through corporate filings that Watkins had acquired approximately 8% ownership of the Wiggles' brand as well as a company directorship in June 2018. Watkins announced her departure from the Wiggles in October 2021 and was replaced by Tsehay Hawkins.

In early 2022, Watkins hinted at the introduction of a new children's entertainment character, Emma Memma, through her social media. The new character was designed to incorporate elements of song, dance and sign language. Toronto-based company Headspinner Productions announced their partnership with Watkins in July 2022 to debut the character in a new pre-school television series titled Emma Memma: Sing. Dance. Sign. Watkins was appointed as an executive producer for the series, to be produced through her company Apricot Sea. The series is expected to begin filming in early 2023 for release later in the year. The character and its design were officially revealed in July; music videos were subsequently released through YouTube. In February 2023, Watkins released a book to go with her Emma Memma character, music and upcoming children's television series. The book was titled Hello, Emma Memma.
