Walter Schreifels (born March 10, 1969) is a rock musician and producer from New York City currently living in Berlin.

In the late 80s, he played in many New York hardcore bands, most notably Youth of Today and Gorilla Biscuits (where he also acted as the songwriter). After Gorilla Biscuits broke up, he formed the short lived Moondog. Moondog would transition into the more metal oriented post-hardcore band Quicksand. He also collaborated with his former Gorilla Biscuits bandmates in the pop-punk band CIV. Later, he helped create the melodic indie rock-styled band Rival Schools. Walking Concert, his most recent project, is heavily influenced by classic British such as Elvis Costello, The Kinks, and The Smiths. A new solo acoustic LP is in the pipeline.

As a producer, he has worked with such hardcore-related bands as Hot Water Music, and The First Step. Recently, he produced the EP Dear Strutter, the first from UK band Cars as Weapons. He is also part owner of the record label Some Records.
