Laemmlein Buttenwieser (Yiddish: אשר לעמלע בן יוסף אריה בוטענווייזער, romanized: Osher Lemle ben Yosef Aryeh Butenvayzer; January 16, 1825 – September 23, 1901) was a German-born Talmudist, linguist, and educator.

He received his semikhah from Seligman Baer Bamberger of Würzburg and from Rapoport and Samuel Freund [Wikidata] of Prague.

He taught at the Talmud Yelodim School in Cincinnati and from 1961 worked as an instructor at the Hebrew Education Society of Philadelphia and at the short-lived Maimonides College in that city.

That same year, he was appointed as a teacher of languages in the New York City public schools, a position he held until his retirement in 1886.

He was survived by his wife, two daughters, and one son, Joseph L. Buttenwieser, a successful real estate dealer and broker.
