Yeah, the Episcopal Church in the US is part of the Anglican Communion.

Though it gets a bit confusing since as of a few decades back when ECUSA decided to fully support marriage equality a few individual congregations left the ECUSA to become protectorates of the Church of England which was at the time more socially conservative; as a result these schismatics call themselves Anglican to distinguish themselves from mdinline Episcopalians. To be clear, I am not one of those.
