Praeclara gratulationis publicae (Splendid testimonies of public [rejoicing]) is an apostolic letter of Pope Leo XIII promulgated on 20 June 1894.

It called for the reunion of Eastern and Western churches into the "Unity of the Faith".

[1] A previous letter on the same subject, entitled In Suprema Petri Apostoli Sede, had been written by Pope Pius IX in 1848.

Praeclara was cited in the encyclical Orientales omnes Ecclesias of Pope Pius XII on the topic of Eastern Catholic Churches.

Leo XIII has also been criticized by Protestant fundamentalists for having declared in the encyclical that "We hold upon this earth the place of God Almighty", which was seen as a sign of the coming apocalypse.
