Mika Alas (Serbian Cyrillic: Мика Алас) is an urban neighborhood of Belgrade, the capital of Serbia. It is located in Belgrade's municipality of Palilula.
Mika Alas is located in the Banat section of the municipality of Palilula, on the left bank of the Danube, where the Jojkićev Dunavac canal empties into the river across the river island (ada) of Kožara. Mika Alas is a weekend-settlement, which means it has no permanent population. It also has no urban connection to other parts of Belgrade (the closest neighborhood is Krnjača, one kilometer to the east). The settlement was named after one of the most important Serbian mathematicians and a passionate fisherman (alas) Mihailo Petrović Alas (1868-1943).
