Mikuláš Jozef Lexmann, OP (October 28, 1899 – July 17, 1952) was a Slovak Catholic priest, one of the most important figures of the Dominican Order in Slovakia.
He was a very active man of wide interests, a pioneer of driving and a pilot.
During the World War II, he was hiding people in danger of their life in the crypt of the Dominican Church in Košice, and is thus registered among those who rescued Jews at the Holocaust Memorial Center in Budapest.
At the beginning of the 1950s, he was interned in several monasteries, where harsh living conditions deteriorated his health and hastened his death.He belongs to the martyrs of the Dominican Order of the 20th century.
In 2013, the Slovak province of the Order approved to initiate a process of his beatification.
