Angika (also known as Anga, Angikar or Chhika-Chhiki) is an Eastern Indo-Aryan language spoken in some parts of the Indian states of Bihar and Jharkhand, as well as in parts of Nepal.

Angika is closely related to neighbouring Indic languages such as Maithili, Bengali, Bhojpuri and Magahi. Historically it was written in a separate script known as 'Anga Lipi'. Later writers shifted to Kaithi Script and eventually to Devanagari Script. Angika has been declared as an additional official language of Jharkhand.

Angika was classified as the southern dialect of Maithili by George Abraham Grierson in the Linguistic Survey of India (1903). He had named it Chhika-Chhiki. However, the Angika speakers now assert its status as an independent language. When the proponents of the Maithili language in Bihar demanded use of Maithili-medium primary education in the early 20th century, the people of the Angika-speaking region did not support them, and instead favoured Hindi-medium education. In the 1960s and the 1970s, when the Maithili speakers demanded a separate Mithila state, the Angika and Bajjika speakers made counter-demands for recognition of their languages.

Angika is not listed in the 8th schedule of the constitution of India.

Angika has the status of "Second State language" in the Indian state of Jharkhand since 2018. It shares this status with 15 other languages, including Maithili.

Naresh Pandey Chakor had written the first ever novel in Angika titled Kisan Ke Jagab.^{[citation needed]}

Angika is mainly spoken in south-eastern Bihar, including most of Munger, the whole of Bhagalpur division and some south eastern parts of Purnia division along with the Santhal Pargana division of Jharkhand. Its speakers number around 15 million people. The region where Angika is spoken is popularly known as Anga, Ang Pradesh and Angika-Belt. Apart from Bihar and Jharkhand states of India, it is also spoken in the Morang district of Nepalese Terai as a minority language. 1.9% people of Morang returned Angika as their mother tongue during the 2011 Nepal census.

Festivals are the core part cultural part of the community. Anga celebrates the festivals of all daith with great enthusiasm and zeal. However, Manasa Puja (Based on Behula Vishahari folklore) and Kali Puja are two examples of intangible cultural heritage of the region. Apart from these, Durga Puja, Saraswati Puja, Chhath Puja, Biswakarma Puja, Basanti Puja, Holi, Guru Poornima, Eid and Karma-Dharma puja too hold a great significance for the region.^{[citation needed]}
