Imoinu or Emoinu (Meitei: ꯏꯃꯣꯏꯅꯨ) is a goddess associated with household, hearth, family, fireplace, kitchen, wealth, peace and prosperity in Meitei mythology and religion of Ancient Kangleipak (Antique Manipur).

Generally, she is portrayed as "an old woman", as her name means "great grandmother" in Meitei language.

The personality of Imoinu and other goddesses like Panthoibi and Phouoibi depict as well as influence the boldness, courage, independence, righteousness and social honour of Meitei women.

[5] The name Imoinu (Emoinu) stands for the goddess rearing the human beings.

[7] Imoinu Ahong Achaubi is a deity for good moral behavior, besides wealth and prosperity.

As a social code of conduct, a Meitei woman should go out from home only after prayers and worship of the goddess and other household deities.

[8] The Meitei people believed that goddess Imoinu lives in the houses of those who strictly obey her favorite social and moral behavior norms.

Imoinu blesses such people with nungai yaifaba (well being and prosperity), watta padaba (having neither shortage nor excess), tekta kaidaba (unaffected by troubles of life) and punshi nungshangba (long life).

[8] According to ancient Meitei text "Lairembi Nongumlol", the Sky God Salailen Sidaba has seven daughters, whom he sent them down to earth to prosper the human civilization.

In that event, a goddess was given the task to be associated with peace, wealth and prosperity.

After the creation of the sky and the planets, Sidaba (Old Manipuri: Sitapa) (the Supreme Being) ordered His wife, Leimarel Sidabi (Old Manipuri: Leimalel Sitapi) (the first woman) to produce another Leimarel.

[10] Nowadays, there is little or no households with proper phunga lairu (traditional fire hearth).

Nowadays, Imoinu Iratpa festival is also celebrated in a larger way in public gathering clubs also.

[11][12] Wherever the festival is performed, seasonal fruits, vegetables and fish are offered to goddess Imoinu.

[13] Imoinu Iratpa is observed every 12th day of the Meitei lunar month, Waakching (Dec-Jan in gregorian calendar).
