What is the difference between a product manager and a product owner?
Product manager is a role covering strategy, discovery and outcomes. Product owner is a specific title from Scrum, responsible for the backlog and for representing requirements to the development team. In many companies one person does both; where they're split, the PO's scope is deliberately narrower.
Different kinds of thing
Product manager describes a job that exists independently of any process framework: understand the market, choose the problems, define success, ship, learn.
Product owner is a Scrum accountability. It exists because Scrum needed a single named person to own the backlog and be available to the development team, replacing the committee-of-stakeholders arrangement that made requirements incoherent.
Comparing them is slightly category-confused, which is why the debate never resolves. One is a profession; the other is a seat in a specific meeting structure.
How companies actually split them
Where both exist, the usual division is: PM owns why and what, PO owns the ordered how. The PM does discovery, talks to customers, defines outcomes; the PO turns that into stories, grooms the backlog, and answers the team's questions during the sprint.
This works when the two are genuinely joined at the hip. It fails when the split becomes a handoff — the PM does research the PO never sees, and the PO manages a backlog whose purpose they can't explain. You get a team executing accurately against requirements nobody can justify.
Jira's history is instructive here: a tool built to serve process compliance, configured centrally, gradually optimising for tracking work rather than understanding why the work exists. Linear's opinionated stance is a direct reaction to that drift.
What to ask in an interview
Titles vary too much to trust. The useful questions: who decides what goes on the roadmap, who talks to customers, and who is accountable for the outcome after launch. Whatever the title, if the answer to all three is someone else, the role is delivery coordination, and it's better to know that before accepting.

Related questions
Is product owner a junior product manager?
Not by definition — in Scrum it's an accountability, not a seniority level. In practice many organisations treat it as a more junior, execution-focused role, which is a local convention rather than what the framework says.
Can one person be both?
Yes, and in most companies below a few hundred people that's normal. Splitting them adds a handoff, which is only worth it when the scope genuinely exceeds one person's capacity.
Which role owns the roadmap?
The product manager, in the sense of deciding direction and outcomes. Where the roles are split, the product owner typically owns the backlog that implements that direction — the sequencing of work rather than the choice of destination.
