MamaRika, born Anastasia Kochetova on 13 April 1989 in Chervonohrad, Lviv region, is a Ukrainian pop and R&B singer, actress and songwriter. She first gained recognition as a finalist on the talent show Fabryka Zirok 3 under the name Erika, then relaunched in 2016 under the MamaRika moniker with a new EP and a broader musical direction spanning funk, soul and hip-hop. Her 2023 duet Люди with KOLA became one of the most-streamed Ukrainian tracks of that year, and since 2022 she has performed at charity concerts in support of the Ukrainian Armed Forces.
The single Kolishnya, released on January 2, 2025 and dedicated to her husband Serhii Seredа, held the first place in YouTube trends in Ukraine for almost three weeks.
In November 2025, MamaRika cancelled part of her scheduled concerts due to an urgent surgery, which she informed her fans about on Instagram.
From September 2025 to March 2026, MamaRika conducted an extensive tour of Ukrainian cities.
In autumn 2022, she released the duet Leleka with Yaktak - a song dedicated to Ukrainians forcibly displaced from their homes.
After the Russian invasion in 2022, MamaRika received permission from the Ministry of Culture to participate in charity concerts and joined fundraising efforts for the Armed Forces of Ukraine.
