Edward John O'Dea (November 23, 1856 – December 25, 1932) was an American prelate of the Roman Catholic Church.
He served as Bishop of Seattle from 1896 until his death in 1932; the diocese was called Nesqually until 1907.
Born in Boston, Massachusetts, O'Dea was ordained to the priesthood in the Diocese of Oregon City in 1876.
He was named the third bishop of the Diocese of Nesqually in 1896.
During his time as bishop, O'Dea moved the episcopal see of the diocese from Vancouver, Washington to Seattle, and the diocese was renamed the Diocese of Seattle.
He was also responsible for the construction of the present-day St.
