The Sony Xperia 5 IV^[a] is an Android smartphone manufactured by Sony. Part of Sony's Xperia series, the phone was announced on September 1, 2022.

The Xperia 5 IV is built similarly to the Xperia 1 IV, using anodized aluminum for the frame and Corning Gorilla Glass Victus for the screen and back panel, as well as IP65 and IP68 certifications for water resistance. The build has a pair of symmetrical bezels on the top and the bottom, where the front-facing dual stereo speakers are placed. The right side contains a fingerprint reader embedded into the power button, a volume rocker and a shutter button. The earpiece, front-facing camera, notification LED and various sensors are housed in the top bezel. The bottom edge has the primary microphone, USB-C port, and SIM/microSDXC card slot; the rear cameras are arranged in a vertical strip. The phone is available in three colors: Black, Green and White. Xperia 5 IV marks the last both Xperia 5 series and all Xperia to feature notification LED, as the successor, Sony Xperia 5 V, has removed the feature.

The Xperia 5 IV is powered by the Qualcomm Snapdragon 8 Gen 1 SoC and an Adreno 730 GPU, accompanied by 8 GB of LPDDR5 RAM. It has 128 or 256 GB of UFS internal storage, which can be expanded up to 1 TB via the microSD card slot with a hybrid dual-SIM setup. The display is a 6.1-inch 1080p (2520 × 1080) HDR OLED with a 21:9 aspect ratio, resulting in a pixel density of 449 ppi. It features a 120 Hz refresh rate, and is capable of displaying one billion colors. The battery capacity is 5000 mAh; USB Power Delivery 3.0 is supported at 30 W over USB-C in addition to wireless charging. The device includes a 3.5 mm audio jack as well as an active external amplifier.

The Xperia 5 IV has three 12 MP rear-facing cameras and a 12 MP front-facing camera. The rear cameras consist of a wide-angle lens (24 mm f/1.7), an ultra wide angle lens (16 mm f/2.2), and a telephoto lens (60 mm f/2.4) with 2.5× optical zoom; each uses ZEISS' T✻ (T-Star) anti-reflective coating.

The Xperia 5 IV runs on Android 12. Sony has also paired the phone's camera tech with a "Pro" mode developed by Sony's camera division CineAlta, whose features take after Sony's Alpha camera lineup.
