--from Wikipedia:

These Christian denominations are among those that mark Ash Wednesday by holding a service of worship or Mass: * African Methodist Episcopal Church * African Methodist Episcopal Zion Church * Anglican/Episcopal churches (excepting most Sydney Diocese churches) * Individual Baptist churches may hold a service * Church of God (Anderson) * Church of the Nazarene * Some congregations of Community of Christ * Some Free Churches * The Liberal Catholic Church * Lutheran churches * Old Catholic Church * Reformed churches (Presbyterian, United Church of Christ, Christian Church (Disciples of Christ), etc.) * Roman Catholic Church * United Methodist churches * Wesleyan churches The Eastern Orthodox Church does not in general observe Ash Wednesday; instead, Orthodox Great Lent begins on Clean Monday. There are, however, a relatively small number of Orthodox Christians who follow the Western Rite; these do observe Ash Wednesday, although often on a different day from the previously-mentioned denominations, as its date is determined from the Orthodox calculation of Pascha, which may be as much as a month later than the Western observance of Easter.
