We present measurements of the angular power spectrum of millimeter wave anisotropies with the APEX-SZ instrument. APEX-SZ has mapped 0.8 deg 2 of sky at a frequency of 150 GHz with an angular resolution of 1'. These new measurements significantly improve the constraints on anisotropy power at 150 GHz over the range of angular multipoles 3000< ℓ< 10, 000, limiting the total astronomical signal in a flat band power to be less than 105 μK 2 at 95% CL. We expect both submillimeter-bright, dusty galaxies and to a lesser extent secondary cosmic microwave background anisotropies from the Sunyaev–Zel'dovich effect (SZE) to significantly contribute to the observed power. Subtracting the SZE power spectrum expected for σ 8= 0.8 and masking bright sources, the best-fit value for the remaining power is C ℓ= 1.1+ 0.9− 0.8× 10− 5 μK 2 (1.7+ 1.4− 1.3 Jy 2 sr− 1). This agrees well with model predictions for power due to submillimeter-bright, dusty galaxies. Comparing this power to the power detected by BLAST at 600 GHz, we find the frequency dependence of the source fluxes to be
