Janusz Wiesław Kaleta (born October 11, 1964, in Łazy, Poland) was a Catholic bishop who was laicized in 2016.

On July 7, 1999, John Paul II created the country's Apostolic Administration of Atyrau, the first with their manager was appointed Father Kaleta.

In an area of over 736,000 km2 (284,000 sq mi), more than twice the size of Poland, live more than 2.2 million people, including more than 2500 Catholics, with a large proportion of foreigners working in oil companies.

On February 5, 2011, Pope Benedict XVI appointed him bishop of Karaganda, while leaving him temporarily as an apostolic administrator of Atyrau.

He resigned as Bishop of Karaganda on July 15, 2014; at that time it was not clear whether this was due to his health problems, the management of the diocese or another reason.
