The Pittock Block is a historic building in downtown Portland, Oregon, occupying a city block between SW 9th and 10th Avenues, SW Stark and Washington Streets, and west of O'Bryant Square.

[4] In May 1913, architects Doyle, Patterson & Beach announced they had been awarded the $700,000 contract to construct the Pittock Block, with construction to begin immediately.

In addition to a deep basement there will be a sub-basement on the part of the block facing Tenth street.

The Northwestern Electric Company, for which the structure is to be erected, will occupy a part of the West Park street side and all of the ground floor on the Stark Street side.

[7][8][9] Other tenants of the Pittock Block include City Club of Portland[10] and the administrative offices of the Oregon Symphony.
