Tehillat Hashem
Tehillat Hashem (תְּהִלַּת ה', "praise of God" in Hebrew) is the name of a siddur, prayer-book, used for Jewish services in synagogues - and privately - by Hasidic Jews, specifically in the Chabad-Lubavitch community. It follows the Nusach Ari prayer rite. The name of the siddur is taken from Psalm 145, verse 21, "Praise of God shall my mouth speak, and all flesh shall bless His holy Name forever and ever." It is produced by the Kehot publishing house.
