Cersei Lannister's IQ — what the methodology actually says.
"Cersei Lannister's IQ" is a popular search. TV Intelligentsia doesn't invent IQ numbers for fictional characters. Here's the honest answer — the show's IQ Score, and what it tells you about how seriously the work treats his mind.
The honest answer
TVI scores shows and films, not characters. Assigning an IQ to a fictional character would be fabrication — we don't have a methodology for that. What we do have: a 0–200 rating of the work's structural intellectual quality, and that score tells you something real about how seriously Game of Thrones treats Cersei Lannister's mind.
Who Cersei Lannister is, and what kind of intelligence the show actually depicts
Cersei Lannister (Lena Headey) is queen-regent of the Seven Kingdoms whose strategic intelligence is the show's most consistent political through-line — the rare TV antagonist whose competence is shown to be precisely the source of the harm she causes. The character's intellectual signature in the show is predatory strategic intelligence, mother-as-political-actor cognition, the rare TV villain whose cunning is explicitly the consequence of her gendered exclusion from formal power.
This is the part of the question "what is Cersei Lannister's IQ" that the search engine flattens. The real question — the one viewers are circling — is whether the show treats his mind seriously. That's the question TVI can actually answer.
What the IQ Score reveals about the portrayal
Game of Thrones scores 155/200 (Stimulating tier) because the show's character work is uneven across its run, but Cersei is one of the consistent through-lines the rubric reads positively. Lena Headey's performance gives the show what the rubric registers as legitimate strategic-intelligence material — a character whose cunning is the structural consequence of her exclusion from the formal hierarchies she has to maneuver inside.
