Loch Scridain is a 15-kilometre-long (9-mile) sea loch, with a west-southwest aspect, on the western, or Atlantic coastline of the Isle of Mull, in the Inner Hebrides, Argyll and Bute, Scotland.

Loch Scridain extends inland as far as the island's only Munro* and extinct volcano, Ben More, a large massif on the Ardmeanach peninsula to the north; the imposing Bearraich hill overlooks the mouth of the loch.

(*A Munro (Scottish Gaelic: Rothach) is defined as a mountain in Scotland with a height over 3,000 feet (914.4 m), and which is on the Scottish Mountaineering Club (SMC) official list of Munros; there is no explicit topographical prominence requirement.)

To the south is the Ross of Mull, the longest peninsula on Mull, that reaches past the sea loch boundary into the Atlantic. Near the head of Loch Scridain is the Aird of Kinloch, a small peninsula that almost separates the main loch from the small inner sea loch, Loch Beg. Loch Beg is fed by the River Coladoir.

Seabank Villa on the lochside at Kilfinichen Bay is the type locality for the mineral mullite.

Loch Scridain to the Ardmeanach peninsula is a lava landscape in which the lava flows have created a layered effect. Basalt lava is rich in minerals, and the land between the crags is green and fertile. There is black basalt, stained orange in places. The orange colour represents the top surfaces of the flow, weathered by the tropical climate of 60 million years ago. There is a fossil tree, with a cave to its right, a large boulder on the shore just below, and a small area of columnar basalt on its left. The cast of the tree is a hollow half-cylinder about 1.2 m (ca. 4 ft) wide, starting just above ground level. Just beyond the tree, there is a black sand beach, and there are in the basalt shoreline slab some older boulders overwhelmed by the lava flow of 60 million years ago.

ⓘ Pseudobrookite ?
Formula: Fe3+2Ti4+O5
Description: Analyses of "pseudobrookite" from the Loch Scridain area indicate that the composition appears to be dominated by the Al2TiO5 component (~36 mol%), whereas the actual true pseudobrookite component (Fe3+2TiO5) only accounts for ~7 mol%, with the remainder almost evenly split between ferropseudobrookite and armalcolite components.
