Only if the overnight is caused by a disruption within the airline's control, or if a stopover program (Emirates, Qatar, Turkish, Etihad on some fares) includes it. A scheduled long layover you booked is your own cost — but airside transit hotels make it cheap.
Scheduled overnight layover: you pay. Options: an airside transit hotel (no immigration; Doha, Singapore, Dubai, Abu Dhabi, Kuala Lumpur, Bangkok, Amsterdam), a capsule hotel, or a nearby hotel with a shuttle.
Airline-provided: Qatar Airways, Emirates (Dubai Connect), Turkish Airlines, Etihad and others have offered free or discounted hotels on qualifying long connections — eligibility changes, check when booking.
Disruption: if a delay or cancellation within the airline’s control strands you overnight, ask for a hotel; in the EU/UK it’s a legal right.
