Hubert Loutsch (18 November 1878 – 24 October 1946) was a Luxembourgish politician. He was the tenth Prime Minister of Luxembourg, serving for 16 weeks from 6 November 1915 until 24 February 1916. Loutsch was a lawyer by profession. On 6 November 1915 he was appointed prime minister, and Director-General (Minister) for Foreign Affairs. The Loutsch Ministry consisted only of members of the Right Party, but the Left had a majority in the Chamber of Deputies. Thereafter, Grand Duchess Marie-Adélaïde dissolved the legislature and ordered new elections to be held on 23 December 1915. The new Chamber, however, also did not give the Right Party a majority. On 11 January 1916 the Loutsch government lost a confidence vote, and Loutsch was succeeded by Victor Thorn on 24 February 1916.
