Terming his election a moment of pride and honour, Yogi Adityanath said that under the guidance of Mr Kovind, the honour of the country would be restored.
The 71-year-old President-elect comes from a village in Kanpur, Uttar Pradesh.
Chief minister Adityanath said it was due to the positive thinking of Prime Minister Narendra Modi and the Bharatiya Janata Party Parliamentary Board that the nation has got "such a fine person as President, one who has an impeccable record in a long public life".
Ram Nath Kovind comes from a rural background and his election will raise the social standing of the rural people and the Dalit community, Yogi Adityanath added.
The Uttar Pradesh chief minister also pointed out that Mr Kovind has always worked for the welfare of the poor, Dalits and the marginalised sections of the society, and that his election would further develop social awareness in the country.
Ram Nath Kovind, backed by the National Democratic Alliance, was elected the 14th President of India today with a massive margin over his United Progressive Alliance rival Meira Kumar in a straight fight.
